Once GATE Overflow Telegram group was taken down because some user shared a copyrighted Aptitude book (of course it was a planned move by someone to take down all other groups in GATE domain). Now, we are sharing the Aptitude PDF compiled mainly from previous year CAT and NIELIT questions. Not yet there but soon we’ll make it GATE CSE PDF standard.

2. Study Tips

Revision : Using Spaced Repetition

Anki: Create Q&A format Anki flashcards for topics difficult to remember or topics rarely asked in GATE

Test Series Timetable: Used retrospective timetable using Google Sheets

Here’s a sample: Color indicates how I felt about my performance and date indicates when I attempted them. Using both these metrics I chose which tests to prioritize during the last 2 months.

 

Solving questions: I divided my notebook into 3 equal parts so that I get used to taking less and narrow space. During your initial period before you start test series you can use cstimer to put yourself under timer pressure and improve your speed(but not at the cost of accuracy). I also used the same pen throughout GATE preparation(Technotip).

Summarized study tips by Barbara Oakley

3. Test Series

First of all, I would like to thank my parents for giving me the freedom to do anything, especially to bear and support me. Our parents work very hard to give us a better life. And also thanks to all my friends, teachers, and aspirants here on GO, Special thanks to Arjun Sir.
My name is Nikhil Dhama, I got AIR 8 (980 score) in GATE CS 2021, This was my second attempt with full-time preparation.
Last year my rank was 1531, I guess this is enough introduction for me, I’ll get to the point now…

 

How did I prepare for GATE 2020?

I followed some coaching material(freely available, wasn't enrolled) blindly, I won’t name it here, Actually it was all my fault all along not following some good content, I did nothing else, not even pyqs. This turned out to be a big mistake. I realized it later after losing a year. Now After preparing again I think it’s for the best that I didn’t get a better rank last year, otherwise, I would have gone for post-graduation with half misconceptions in my mind and that would be a disaster. I didn’t even deserve 1531 rank last year, it was too good for my preparation level, preparation was way poor (soon you will know why I’m saying so).

 

What makes me drop and prepare again?

I enjoy learning stuff, I like solving mathematical problems with low-sound music :p, so I was sure for post-graduation. For this reason, I did not sit for campus placements, because I didn’t want to have a second thought if I had a placement in my hand. I left no choice for myself other than a drop or taking some college with this rank only...

 

Why didn’t I apply for some other tests like PGEE, ISI, CMI, last year instead of repeating?

No doubt there are many good colleges in India, but after giving Gate 2020, I realized my concepts are not that strong, I’m missing something, and second I could do much better. This wasn’t my best, I wanted to try again.

I decided right after the result of GATE 2020 that I will prepare again. But the first step was to analyze the mistakes I have done throughout my preparation and during those 3 hours inside the examination hall.

 

Mistakes I did last year...

The first mistake I made was to trust in the coaching material and their false claims, I got a bit lazy, the second big mistake was not solving pyqs.
I was overconfident last year, during that 3 hours I could not even read all question, left 8-10 questions unread. This shows a lack of practice and time management, as I invested lots of time on few particular problems, that turned out to be wrong later :( Maths is my strong suit, and I couldn’t solve a simple calculus problem there. So I had to work on all these things and improve myself.

 

Steps I took to counter those mistakes...

I checked who is going to conduct GATE 2021, found out it’ll be IITB most probably. I had a very bad experience with JEE Adv 2015, I knew what these people usually do. This gave me a hard feeling that what if I fail again? anyhow I got through that.. and started looking for the solution to my mistakes.. decided to read books thoroughly this time.
I researched for 10-15 days and gathered all my study material for the preparation. My first stopping point was GO, found almost everything I need. Enrolled in the test series as early as I can (gave tests from GO and applied only). and improved on each of them one by one.

 

What was my schedule for preparation for GATE 2021?

I started slowly around 4 to 6 hours a day, enjoyed the rest of the time, watched some movie or anything, then shifted gear in July and changed my preparation time from daytime to nights.. started studying from approx 3 PM till I could, with small breaks in between. Every day studied at-least till 4 AM, for some days I stretched it till 7 AM, depending upon how much interest I have in that topic. This was my daily schedule, with minimum full-day breaks.

I divided the weekdays into two parts, Mon-Fri study with the same schedule, Sat-Sun solve pyqs from the topics I covered earlier, usually a different topic from what I studied during that week and give a test or revise everything I studied during the week or any topic if I got stuck in pyqs. This way I was doing both preparation and revision side by side.

Took a break for 20-25 days in Oct, had to give final sem exams.. started back again.. and finished the syllabus by the end of Nov. Only a few maths topics were left... I was already confident in those topics. I started giving tests late, from the beginning of Nov, I don’t suggest you do it. I had less time and had to cover lots of stuffs.. also sharp memory helps me keep things longer in my mind. Was doing well in tests.

By the end of Dec, I was done with the full syllabus, one-time revision, and all pyqs.
Changed my schedule from Jan, admit card was out, got the morning session, so I had to adapt myself to that timing.. took me 15-20 days for it... In Jan, gave a mock test almost every single day, analyzed my mistakes during the day, and revised in the evening. Every third day of the month I solved one previous year GATE paper as a mock test (from 2011 to 2018 at sets).

Appeared in GO mocks, almost everybody here knows about those.. took a test by Ruturaj Sir 2 days before the exam.. just to have the feeling of a hard paper and be ready for the worst-case as I was already expecting a hard paper.
Gave all these tests for time management, GO subject tests were an informative and conceptual test for me.

NOTE: you need not follow this schedule at all, I like studying at night.. and wanted to read everything in a short time, that’s why this schedule.. make your schedule at your convenience, which suits you the best.

 

What resources did I follow?

You can find them here.

While reading books, I found out I had many misconceptions and was lacking basic details of almost all of the concepts.. that’s why I didn’t deserve any better rank than 1531 last year.

 

How much stress was I having during preparation?

You can imagine by reading my schedule... side by side I was going through emotional stuff which needs to be taken care of, I decided to keep all such thoughts aside and kept focusing on my preparation, sometimes I even started to feel like a failure that I couldn’t do anything and many more stuff.. but I made it through, the good thing is I enjoyed studying all these concepts that’s why I never got bored or exhausted with my schedule. I wanted to give my best.. and I was targeting 90+ marks, so it was all worth it. I would like to add that there was a time once where I couldn’t read or study anything for 8-10 days, it’s alright as long as you make a comeback, also it’s necessary to take small breaks, I used to play online cards and video games, watch movies during my breaks. Just find your comfort zone.

 

How did those 3 hours inside the examination hall go?

To be honest I wasn’t feeling like I’m going for the exam until I reached the center and sat on my allocated seat... Started to get some butterflies after sitting there.. plus I prepared myself to attempt the exam in a single pass without revisiting too many questions.

It’s almost 9:30 AM and the exam starts, directly went for CS section, the first question was based on the covariance of two parameters of a distribution, damn I left this topic just because it was not required for GATE, I knew one part of it.. but couldn’t take a risk of -0.66.. so just left it.

10 mins past I have seen 4 questions, only 1 attempted.. situation got a little bit tensed now. I closed the question window so that my mind won’t divert by looking at how much I have attempted.. started attempting one by one.. with 15 mins spare, I was at the end of the paper, I opened the window again, and felt a bit relaxed, only 9 questions were unattempted.. attempted 5 more in that 15 mins (4 of them turn out to be correct).. so in total, I attempted 61 questions, 52 correct 9 incorrect, 8 out of 9 are MSQ or NAT so no negative here. Only 0.66 negative marks in one question.
 

Final result

The first official answer key was out, one big debate on one aptitude question, the official key was against me ;-; It could cost me a lot, but finally things settled in my favour, and both answers were given right in the final key.

I got 80.33 marks in set 1 (before normalization). Now I just had to wait for the final result.

Got AIR 8 in the final result.. still feels like I’m dreaming :))

 

 

I hope this covers almost everything. If anyone has any queries, feel free to ask.

Given an infinite sequence of numbers $<a_0, a_1, a_2, a_3, . . .>$, the (ordinary) generating function for the sequence is defined to be the power series:

$A(x) = \sum_{i=0}^{\infty}a_ix^i =  a_0 + a_1x + a_2x^2 + a_3x^3 + . . . $ 

 

Consider the binomial expansion of $(1-x)^n$, where $n\in \mathbb{Z}^+$

$(1-x)^n = \sum_{i=0}^{n}\binom{n}{i}(-x)^i$

$\quad = 1 - nx + \frac{n(n-1)}{2!}x^2 – \frac{n(n-1)(n-2)}{3!}x^3 \ldots +(-1)^k\frac{n(n-1)(n-2)\ldots (n-k+1)}{k!}x^k .\ldots + (-1)^nx^n $

 

Note that if we substitute $n$ with its negative value, the expansion fails to converge, i.e.

$(1-x)^{-n}  = 1 - (-n)x + \frac{(-n)(-n-1)}{2!}x^2 - \frac{(-n)(-n-1)(-n-2)}{3!}x^3  +\ldots $

$\qquad =1 + nx + \frac{n(n+1)}{2!}x^2 + \frac{n(n+1)(n+2)}{3!}x^3  +\ldots $

$\qquad = \sum_{i=0}^{\infty}\binom{n+i-1}{i}x^i$

 

(Expansion of $(1+x)^{-n}$ is the same, but with alternating signs. Try to derive it yourself)

In 99% of the cases, we’ll be dealing with $(1-x)^{-n}$ as far as GATE is concerned.

 

Applying the above formula for $n=-1$, we get

$(1-x)^{-1} = 1 + x + x^2 + x^3 + x^4 + . . .$

 (Notice that it’s a generating function for the sequence $<1,1,1,...>$)

 

Similarly for $n=-2$, we get

$(1-x)^{-2} = 1 + 2x + 3x^2 + 4x^3 + 5x^4 + . . .$

(Notice that it’s a generating function for the sequence $<1,2,3,4,5,...>$) 

 

**Operations on Generating Functions**

Let’s assume two generating functions:

$A(x) =  \sum_{i=0}^{\infty}a_ix^i $

$B(x) =  \sum_{i=0}^{\infty}b_ix^i $

 

  1. $\forall \alpha, \beta \in \mathbb{R}$,  $ \alpha A(x) + \beta B(x)$ is another generating function $C(x)$ where
$c_i = \alpha a_i + \beta b_i$,    $ \forall i \in \{0,1,2,3,...\}$ 

 

 

  1.  $A(x)\times B(x)$ is another generating function $D(x)$ where
$d_i = a_0b_i + a_1b_{i-1} + a_2b_{i-2} + . . . + a_ib_0$,    $ \forall i \in \{0,1,2,3,...\}$

 

 

  1. $A^2(x) = A(x) \times A(x)$ is another generating function $E(x)$ where
$e_i = a_0a_i + a_1a_{i-1} + a_2a_{i-2} + . . . + a_ia_0$,    $ \forall i \in \{0,1,2,3,...\}$

 

 

  1. $A(kx)$ is another generating function $F(x)$ where
$f_i = k^ia_i$,    $ \forall i \in \{0,1,2,3,...\}$

 

 

  1. $x^mA(x)$, $m\in\mathbb{N}$ is another generating function $G(x)$ where
$g_i = 0$,     $\forall i \in \{0, 1, 2, …, m-1\}$ 
$g_i = a_{i-m}$,    $\forall i \in \{m ,m+1, m+2, . . .\}$

 

 

  1. $(1-x)A(x) = A(x) – xA(x)$ is another generating function $H(x)$ where
$h_i = a_i – a_{i+1}$,    $\forall i \in \{0,1,2,3,...\}$

 

 

  1. $\frac{A(x)}{(1-x)} = A(x)[1+x+x^2+x^3+...] = A(x) + xA(x) + x^2A(x) + . . . $ is another generating function $J(x)$ where
$j_i = a_0 + a_1 + a_2 + … + a_i$,    $ \forall i \in \{0,1,2,3,...\}$

 

 

  1. $A’(x) = \frac{d}{dx}A(x)$ is another generating function $K(x)$ where  
$k_i = (i+1)a_{i+1}$,    $ \forall i \in \{0,1,2,3,...\}$

 

(**Note: Try deriving all the 8 operations above, pretty easy and mechanical)

 

Kind of questions that may be asked in GATE:

 

  1. Given something like $(a_0x^k + a_1x^{k+1} + a_2x^{k+2} + ...)^m$, find the coefficient of $x^p$, where $k,m,p, a_i \in \mathbb{N}, \forall i \in \{0,1,2,...\}$ 

Approach: If all the coefficients are $1$, take $x^k$ as common and bring it out, i.e.

$[x^k (1 + x + x^2 + x^3 + ...)]^m = x^{km}[1+x+x^2+x^3...]^m = x^{km}[\frac{1}{1-x}]^{m} = x^{km}(1-x)^{-m}$

 

Now $(1-x)^{-m}$ is simply $\sum_{i=0}^{\infty}\binom{m+i-1}{i}x^i$. Putting everything together, we just need to find coefficient of $x^p$ in the expression:

$x^{km}\sum_{i=0}^{\infty}\binom{m+i-1}{i}x^i$.

If we let $p = km + z$ where $z \in \mathbb{N}$, then the coefficient of $x^p$ is just the coefficient of $x^z$ in $\sum_{i=0}^{\infty}\binom{m+i-1}{i}x^i$ which is simply $\binom{m+z-1}{z} = \binom{m+p-km-1}{p-km}$

 

If not all the coefficients $a_i$ in $(a_0x^k + a_1x^{k+1} + a_2x^{k+2} + ...)^m$ are $1$, then like before, bring out $x^k$ and simply try to bring $(a_0 + a_1x + a_2x^2 + ...)$ into closed form (maybe use the “manipulation” technique as mentioned below), then raise it to power $m$ and rest of the calculation is pretty similar to the one I wrote above. Pretty time consuming and tedious stuff depending on what the coefficients are, but considering GATE, the expression should be a direct expansion of $x^k(1\pm x)^{-n}$ where $k,n \in \mathbb{Z}^+$

 

 

  1. Given an expression for calculating each coefficient of some generating function (i.e. each term of the infinite sequence), find the closed form of that generating function.

Approach: Check if the expression involves $’+’$ symbol. If it does, then the resulting generating function will be a sum of generating functions generated by each of those terms. For example, if $a_i = 7i + 6i^2$, then generating function of $A(x)$ is simply the sum of generating functions of the sequences $<(7\times 0), (7\times 1), (7\times 2), . . .>$ and $<(6\times 0^2), (6\times 1^2), (6\times 2^2), ...>$ respectively.

If there’s no $’+’$ symbol, then it’s simply the generating function generated by that single term. Here’s an example to make things concrete:

 

If each term of an infinite sequence $\{a_n\}$ is calculated as $a_i = 7i + 6i^2, \forall i \in \{0,1,2,3,...\}$, find the generating function generated by the sequence $\{a_n\}$ 

Ans: As stated above, if we assume $A(x)$ to be the generating function generated by the sequence $\{a_n\}$, then $A(x) = B(x) + C(x)$, where $B(x)$ and $C(x)$ are generating functions of the sequences $<(7\times 0), (7\times 1), (7\times 2), . . .>$ and $<(6\times 0^2), (6\times 1^2), (6\times 2^2), ...>$ respectively.

 

$B(x) = 0 + 7x + 14x^2 + 21x^3 + … = 7(1x + 2x^2 + 3x^3 + ….) = 7x(1+2x+3x^2+4x^3+...) = 7x(1-x)^{-2}$

 

Calculating $C(x)$ is a bit tricky.

$C(x) = 0 + (6\times 1^2)x + (6\times 2^2)x^2 + (6\times 3^2)x^3 + … = 6(0 + 1^2x + 2^2x^2 + 3^2x^3 + ...)$

 

Using the “manipuation” technique (more on it below),

$(1-x)^{-2} = 1 + 2x + 3x^2 + 4x^3 + ….$

$=> x(1-x)^{-2} = x + 2x^2 + 3x^3 + 4x^4 + ….$

$=> \frac{d}{dx}[x(1-x)^{-2}] = 1^2 + 2^2x + 3^2x^2 + 4^2x^3 + ….$

$=> x[\frac{d}{dx}[x(1-x)^{-2}]] = 1^2x + 2^2x^2 + 3^2x^3 + 4^2x^4 + ….$

 

Therefore, $C(x) = 6[x[\frac{d}{dx}[x(1-x)^{-2}]]]$. Solving it, we get $C(x) = 6x(1+x)(1-x)^{-3}$.

Putting everything together,

 

$A(x) = B(x) + C(x) = \frac{7x}{(1-x)^2} + \frac{6x(1+x)}{(1-x)^3}$


”Manipulation” technique (or what I like to call it)

Given a generating function $A(x) = \sum_{i=0}^{\infty}a_ix^i$, whose closed form is not immediately apparent, start off with a generating function $G(x)$ of the form $\frac{1}{(1\pm x)^n}$ (or even something more complicated) which looks kinda similar to that of $A(x)$. The idea is to manipulate $G(x)$ by a series of multiplication/differentiation/integration ..or whatever operations, to make the RHS of it similar to that of $A(x)$.

 

Here’s a quick example of what I meant. Consider $A(x) = 1^2 + 2^2x + 3^2x^2+ 4^2x^3 + ...$

It’s looks kinda similar to $(1-x)^{-2} = 1 + 2x + 3x^2 + 4x^3 + . . . $.

So we can manipulate it like this:

$=> (1-x)^{-2} = 1 + 2x + 3x^2 + 4x^3 + . . . $

$=> x(1-x)^{-2} = x + 2x^2 + 3x^3 + 4x^4 + . . . $

$=> \frac{d}{dx}[x(1-x)^{-2}] = 1 + 2^2x + 3^2x^2 + 4^2x^3 + . . . = A(x) $

 

Therefore $A(x) = \frac{d}{dx}[x(1-x)^{-2}]  = \frac{1+x}{(1-x)^3}$

 

(These were pretty much my notes on Generating Functions for GATE 2020. Although this should pretty much cover everything needed for GATE, do refer to explanations from books as well (I recommend ”Principles and Techniques in Combinatorics” by Chen Chuan Chong) and of course, practice the questions (a lot of them !!))

PRAGYS APP

Since many people are not fully aware of the features of Pragy’s app, I’m listing them here:

  1. You can calculate your mark by giving your response URL here: https://gateoverflow.in/mymarks/index.php No user details required.
  2. You can get the current rank (among those who used the app) as well as the estimated rank and score from here: https://gateoverflow.in/mymarks/VisualizeMarks.php
  3. Regarding the accuracy of the predictor you can see what happened last year: https://docs.google.com/spreadsheets/d/1VuLslsr6ONupFJHXmQWQlCyR0FoUP2Oa-zthqE7tl1A/edit#gid=739634420
  4. Regarding where all to apply, you can use the College Suggestion part of the app here: https://gateoverflow.in/mymarks/ScoreToColleges.php?score=633.24
  5. Almost all the good options are given above though data for some reserved categories are missing as they weren’t available anywhere. 
  6. MUST read out the points given in the College Suggestion part.

Hi, all, toppers of this year, congratulations to you for your success.

Now, many of you have got good ranks which is enough to get a TA position in top IITs. Some some of you may have to face RA interviews.

In most of the IITs, the autumn semester starts from July. Considering that, you have ample amount of time to learn something relevant to the topics that you are willing to pursue in IITs. This would help you to decide your area of interest ( for your master thesis and seminar and all ). 

There is a Moodle site called "go-classroom" ( http://classroom.gateoverflow.in) initiated by Arjun Suresh Sir last year. You may join the M.Tech section to get updates related to M.Tech courses, relevant lecture, assignments, useful links, and many more useful stuff. 

The section is not updated yet, but it will be updated soon.

Hi everyone! My name is Rishabh Gupta and I secured AIR - 2 in GATE 2018. Marks: 83.00. Credit goes to my parents and GATE OVERFLOW.

I am a final year student in a tier-3 college. It was my first attempt. Even being in a central university, we have zero placements. Really, not a single company visited our campus this year for CSE(till now), not even the mass recruiters like TCS and Infy.
But I think that is why I got this rank. There was no other option, but to study and prepare for a competitive exam which offers a decent chance to excel in the professional sphere.

Whatever I am writing here is a part of my own viewpoint. Many might disagree with me. I would, rather, like to suggest you do not follow me blindly but rather analyse yourself and do what suits you best.

I always followed standard books during my BTech, even when teachers forced us to follow books of some local authors. This resulted in a relatively not that good performance in my college exams, but I knew that I was building concepts instead of mugging up and rotting my knowledge.

It would be my suggestion for you all aspirants to follow the standard books. It might take more efforts, but its worth it. Don't ask for notes from toppers, seniors, etc. but create your own. When you will make notes all by yourself, you will understand better. There is no secret to success, It's all up to you as you have to do the intended labour. Your teachers can teach you, blogs can motivate you, seniors can guide you, coaching people can tell you everything, but it's YOU who have to put your brain to work.

I started proper GATE preparation from July 2017. I prepared the complete schedule up till the exam.
I went through books of all subjects in this duration. Since I had already been through them earlier, so it was not difficult for me to do it again.
You should be clear about when and how you will do each and every subject. Create your plan according to your grasp in each subject. My plan was:
July - Discrete Maths (started with this because this is the base for cs)
August - C, Data structure and Algorithms (These were comparatively easy subjects for me since I did competitive coding)
September - TOC and Compiler Design (Compiler Design took a lot of time since I was studying it for the first time, so I made sure to do TOC quickly as I had a grip on it already)
October - DLD and COA (DLD is considered easy. COA can take time and I spent a lot of time in clearing my doubts)
November - OS (only 1 subject because of 7th sem exams)
December - DBMS and Networks (Don't take networking lightly!)
January - Aptitude and revision (and also Engineering Maths, which I kept neglecting)
February - Relax and gave the exam

Although, I set the deadlines but sometimes was not able to achieve it and extended a day or two. Make sure you stick to your plan and make changes to it as you proceed. The key here is consistency. Work hard, DAILY.

After reading books and preparing notes, I used to solve previous year GATE questions. And often got stuck. GO comes to the rescue at this point. There are so many aspirants like you, here at GO, who will help you in resolving doubts. You should also engage in helping others and clearing their doubts, this will, in turn, will clarify your concepts too.
For the name of the books and relevant chapters see this: https://engineering.careers360.com/articles/gate-2017-topper-interview-ravi-shankar-mishra-air-3-cs
You can find all book's pdf on the internet.

COACHING
I didn't attend any coaching(mainly because there was no coaching centre near me).
I felt that they just help us in mugging formulas, without giving an intuition of the core concepts. I have seen their study material, it often consists of "points to remember", and they expect you to memorize them(or rather to say mug them up), without having much of understanding.
Mugging up formulas is not at all required(at least this is what I believe in Computer Science it's all about Common Sense). I think if you intend to memorize the formula then it indicates that you do not have a hold over the concept. For example, people often try to "mug up" the formula for the average access time in cache (and Virtual memory) and often get confused when to use what. But once you understand that how the cache works, the confusion won't arise. You should understand the meaning of the terms related to it like hierarchical access or simultaneous access, miss penalty, main memory access time, etc.
Similarly, there are concepts in TOC like closure properties. Don't try to learn it by-heart, instead, try to make sense out of it, try to develop an intuition for it, try to visualize the concept, read the books and try to understand through the lines. Search on the internet, you will find lectures, ppts of great university's professors. When you began searching on the internet, you often come across new things surrounding that concept. It's YOU who need to browse things. No one is going to spoon feed.
It might not be possible to grasp everything and you might need to just memorize the formula sometimes due to time constraints. It's okay, everyone does it. But try to keep it at a minimum level. I was not able to understand a lot of things like probability distribution formulas, Catalan numbers, and a few other concepts. So I just learnt it by heart but you should try to by-heart things as minimum as possible. Mug it only when it is the last option.

I have already said a lot against "Coaching". But this should not be taken in a bad light, some of them might be worthy of their popularity (since I never went to one). But still, they are not the "masters" of their field. One can learn directly from the MASTERS of CS. Video lectures by NPTEL, MIT, Stanford, Aduni(Shai Simonson), etc. are all available for free. Those are some of the professors who developed these concepts, so you can't doubt their knowledge.
Going for coaching or Self-preparation? totally depends on you. Ask yourself. "Can I do it without coaching?"

STUDY MATERIAL
People often ask me for this, "Without the help of coaching material from where you have practised?"
1. First of all, GATE PREVIOUS YEAR questions. I am emphasizing on this a lot. These are really really very important.
These will give you an idea about the type of questions you will be confronting to. So solve them at least twice.
2. Then questions from CMI, TIFR, ISRO, etc.
For above points(1 and 2) GOPDF is best. It's better than any question bank book because you can comment and argue in GO, and attain a deeper understanding. And it's free!
3. Solve questions from standard textbooks. Those questions are more about thinking and letting your brain do some hard work.
These are not MCQs which you just try to look out for correct answer by eliminating options. Rather these are generally proofs or "finding an efficient algorithm" types. Here seeking the answer is not that important rather your approach matters. You might not be able to solve all of them, but at least try to grab a few. The time you will spend in thinking about the problem will be fruitful, whether you find an answer or not. It will increase your thinking capability.
At least understand what the question is asking. If you are not able to solve yourself, then search for solutions.
4. If you still have time, search for IIT, MIT, Stanford, CMU, etc. assignments. They are great. Be aware that you don't step far away from GATE syllabus. Caution: Some of these questions might be very difficult from GATE point of view. But at least giving it a try will help you. You will get a feeling that GATE questions are pretty easy as compared to them.
5. See questions here at GO. Many people add questions from their study material or test series. You can have a look at these questions too.

Also, try to modify GATE questions and try to develop an understanding about their solutions.

TEST SERIES
Test series are important. They might not increase your knowledge, but provide an environment of competition and help you in self-analysis.
GO and Virtual Gate test series are great. I would like to thank Techtud Group for providing free quality tests.
Other than these, I joined ME test series, but it wasn't so qualitative like they advertised it to be. I was hardly able to cross 70+ in these test, mainly because there were so many wrong questions. Nonetheless, taking them can be advantageous.
Importance of test series is that you can analyse your mistakes and they help you in time management. Try to give the exam at the same time as of GATE, it will train your mind to work at that time.
Don't bother much about rank. I was never in top 10 in ME full-length MOCK test. And I saw people getting 90+ in these tests.
Silly mistakes, you cannot eliminate, but can reduce them significantly by practice.
A single mistake of writing 0.231 instead of 0.0231 made me 2 instead of AIR 1  :p

At last, a rank is just a number, it does not prove your intelligence or brilliance(but yes they give you admissions to good college). I have seen many people here at GO who are far more knowledgeable than me (like the LEGEND, Habib Sir, and many more). They had written many great answers here, and I often asked doubts from them. After a certain level of preparation, almost everyone comes at an equal level. It just boils down to what you are going to do in those 3 hours. How you are going to manage the pressure. I was lucky enough to do good in those 3 hours. Take proper rest before the exam day and be confident.

Thank you very much Arjun sir for this platform, thanks to Bikram sir for so many good tests(which are way better than paid ones), and thanks to all seniors here at GO, whose blogs and answers motivated me. And Thanks to all other active users of GO. It was a great experience preparing with you people :)

All the best to future aspirants. You can message me anytime, I will be glad to help :)
Thank You!
