So i graduated from a decent government engineering college in electrical engineering. I always had an inclination towards computer science, and during my bachelors days, used to create websites for fun. I wanted to do m tech in computer science related field, and when i checked the subjects and their syllabus for GATE CSE, i was initially thrilled to be learning such interesting topics, but realized how tough it is going to be for me, someone with basically 0 knowledge about any subject except Data structures and Algorithms.

This is where Gate Overflow came to my rescue. Whenever i couldn’t understand the logic behind any Gate problem, i checked the...

Without this platform and the people behind it working tirelessly to maintain its quality (including all the good people in the FB group), I would not have been able to succeed. I’m not the typical applicant – I graduated in 2014 and have 5+ years of product startup experience. I had to start preparation from scratch in 2019, and by scratch, I really mean from zero – I graduated with CS BTech from tier 3 and my CS background was nowhere close to the level needed by IITs. Thanks to Bikram Ballav’s “what to read” series, I could even begin to build the necessary background for GATE. I really enjoyed studying computer science and it gave me an enlightened...

I kept using gate overflow for solutions which I didn’t understand when I was solving PYQs from my classes book. In November I came across GO PDFs. I solved all the questions again during December – January and checked many solutions and comments. Many solutions completely changed my understanding to topics. The community is the best with so many knowledgeable people and aspirants. We also get multiple approaches to same problem as many users have uploaded their own solution. Gatecse website also has amazing resources like video links, question papers, etc. I did not use it much but it was also very helpful. Also, the rank predictor was so perfect that it was...

Huge thanks to GO and the community for making a dream come true!

My GATE 2020 marks were 42 and my preparation was also not up to the mark. So I decided to drop out and give my best for Gate 2021 and in the process decided not to take any online Coaching. I Completed GO PDF 3 to 4 times during my preparation which helped in boosting my confidence. Also, a huge thanks to the GO Test Series community. The level of the questions was just perfect to push myself just a little more to get more marks. Slowly but eventually, I saw myself grow from 30 to 75-80% marks. I was hoping to get the same result in the main exam and thankfully i got 71.67 marks(after...

My name is Shaswat and i have completed my Bachelors in Electrical engineering in 2018 from NIT Jamshedpur and was working in a Steel Industry till April last year. After that i decided to quit my job and started my preparation for Gate in Computer Science and secured an All India Rank of 13. 

After my 10 month long preparation I genuinely believe that Gate-CS can be cracked by anyone irrespective of their stream. If you have a tendency to think in a logical way then cracking Gate will be a piece of cake for you.


Although there are a lot of preparation strategies online but still i would like to briefly share my...

Hello everyone, This is Rajnandani Shaw and I have secured AIR 312 with marks 65.3(Gate score 779) in GATE 2020 and also selected as Scientist B in DRDO. I am neither a GATE topper nor from IIT/IIIT/NIT's but just an average student from a very normal engineering college just like many. I am a 2016 batch passout and had prepared for GATE with a full-time job. I am very thankful to Arjun sir and GateOverflow team for such a wonderful platform which had helped a lot during my entire preparation. This is my first post on GateOverflow. GO previous year's questions hard copy and goclassroom are very useful for gate preparation. GateOverflow is a must for all preparing from...

Hi, I am Suraj Kesharwani, I have scored AIR: 372 in GATE 2020. My Gate-Score is 764. This was my third attempt. I had to leave my job earlier in June 2019 to prepare seriously as I decided this would be my last attempt. My previous ranks are 5793 and 7613 in GATE 2018 and 2019 respectively. 

I want to thank my family, GO Community, and my friend/ Mentor Abhishek Shaw. He has cracked GATE in 2019 with AIR: 175 and has also inspired me to leave my job and prepare full time. This blog is in continuation of his preparation strategy as I have also followed it with some improvements. You...

I have already covered my preparation experience in a separate article here. So, I will try to keep this post short and cover main pointers for working professionals and also about how I used GO.

Main pointers for working professionals:

I have secured AIR-(202) out of 97481 students( 99.79 percentile) in GATE CS-2020 with marks 68/100 and my gate score is 811/1000. Currently , I am in my final year and  pursuing my B.Tech in Computer Science & Engineering from  Feroze Gandhi Institute of Engineering & Technology, Raebareli (U.P.).  I always had a dream of getting into IIT and with that dream after my 10+2, I went to KOTA FACTORY but was unable to crack it but the most important part was what I have learned from the failure and throughout the journey. After that anyhow I took admission in a state University Tier – 3 college.

Now I will describe shortly the each...

Hi, This is Vishal Gourav, I work at TCS,Noida presently and prepared for GATE 2020 while having a full time(9-6) job.

Short Back Story: I was never great in studies not because I couldn’t understand the concepts but because I lacked the hard work and discipline. While I was pursuing B.Tech from JSSATE,Noida I was content with just finishing up with my studies finally and getting into a job,start earning money and spending it.

In 2019, I had given GATE with 1 month preparation and got 38.33/100(AIR:7045, Score:448). Though the score was not much to be proud off but for the first time in my life I had enjoyed...

Hello Everyone,

I’m Aditya Pradhan, a final year student of Information Technology at a state government college in Udaipur. I have secured $AIR\ 312$ in $GATE\ 2020$. I expected much better rank before the exam, but was not able to attempt more questions (attempted only $52$) and was depressed because of this. But hopefully I got only $4$ or $5$ of them wrong and landed at this rank. Now, I am preparing for IIT Kanpur M.S., IIT-B M.Tech. RA and IISc CDS Coursework and CSA Research interviews and hoping that my semester exam dates don’t clash with any of them.

Regarding my preparation journey, I used to study my semester subjects through standard...

Quick Read : Follow the resources given in Those are the best that you can find online. Solve GO pdf thoroughly unless you've mastered the concepts involved in the PYQs. Read comments and different approaches for answers. Take test series if you've time but don't take the marks seriously :P

A big thanks to GO community. Here you will find everything you need to strengthen your concepts. Best thing about GO is that you can argue about answers, have healthy discussions and get to the root of why the solution is the way it is. Aspirants of GATE CS are fortunate to have this platform.

I fell sick in last week leading...

My Background

During my 11th-12th I studied in a school where there were no one preparing for JEE. Everyone just wanted to get into some local engineering college. Best scenario possible was getting into some private college with tuition-fee-waiver. If one cannot make it into some engineering college then he/she would join BSc or something. That’s what our teachers told us. I didn’t know what’s the difference between IITs and local colleges is. Actually, at the time of solving MCQs from books we skipped the question if it had been asked in previous JEE papers :). That was the scenario. I really find it very frustrating sometime...

I am a final year student at IIIT Bhubaneswar of CSE branch. I secured rank 178 this year with 68.67 marks and 818 score. This is my first post on gate for all future gate aspirants.This was my first attempt of gate and I studied with the help of video lectures and then self study.GO helped a lot during my preparation.Whenever I faced any doubt on any topic or faced trouble solving any question I would search it on Gateoverflow, and everytime my doubts were resolved.Students who prepare by online courses or do self study,GO is life saviour for them.Because eventually you will have trouble solving questions and you would not have anyone to resolve your doubts, that time...

Well, after my BTech in EXTC, I had managed to get a good job at Wipro in Telecom domain. However, after few months in the IT work, I started feeling that this is not the place where I belong, I felt I am born to do something more, the IT work can be taught to any other BTech guy, and he was any day replaceable. I didn’t wanted to be that replaceable person, and wanted to do more fruitful work, and I also wanted to study more, and then I thought of giving GATE, and yes, I wanted to give GATE in CS.

 It was a difficult decision for me and a risky one too, to leave my well paid job and go back to studies, that too in a...
