Schedule for GATECSE 2021

The schedule followed by GO for GATE2020

Please do not listen to what random people say about the schedule. This is a relaxed one and so you should not keep any topics for later thinking you have time. 

Please see here for GO Book for GATECSE 2020

Advantages of following this schedule:

  1. It is not the only good schedule possible but is one schedule where subject dependencies are met 
  2. You can ask any doubt from the topics already covered in the schedule here with the tag go-classroom and those will be answered with priority
  3. Preparation materials including reference links are provided on GO classroom as per the schedule
  4. Even if you are joining late, you can adjust your schedule accordingly - most assignments in GO classroom will allow late submissions and this schedule will be over by November end.
  5. Extra points to be followed will be updated here.

I've created a Google Calendar of the above schedule, and it's here. It's useful if you have an android phone, and use calendar, or Google assistant, or chrome browser. 

we can use MOODLE app to access GO CLASSROOM as a app with all the features.

Can we complete them at our own pace? I mean can we complete them faster than the assigned schedule as the content already exists?
Hi @Arjun sir I am not able to add the blog in my favorite List.

Only Questions can be added, is this a bug?
I'm not sure of it. Will check it -- it should work (might be having some bugs).

So @Arjun sir, will you add materials for Verbal and Quantitative ability on the course page? Or we have to cover it ourselves using our preferred material?

Yes, there won't be any material additions other than those on the GO classroom as of now. But for some topics revision stuffs might be added -- no need to wait for those. You should cover topics from standard resources and for aptitude mainly do all previous GATE questions and if one looks for Aptitude material, it will include 90% of CAT materials.
Thank you very much. This calendar is helpful.

@Arjun Sir, will there be a test on Quantitative Aptitude?

@Arjun sir how should I prepare for GATE 2021 ? Should I start with the CS subjects?
Thank you very much.
How to register for GO Classroom for those who already have account in gateoverflow?

I am not able access gate classroom, my credentials which i got last year are not working

my email id is [email protected]

I am not able to go beyond the update profile page. Every link I click on redirects to update profile. On clicking on the update profile button I am getting this error

Error updating user record
where is the test link for this week(july 15-21)?
All the tests scheduled to be added here are canceled.
@Arjun Sir ,where can i access the tests,started from may onwards and get access for all the tests now.Do help me,Sir.
but why ?

@Arjun Sir , I am not able to enrol for Compiler Design Classroom course. Can you please help me with that?

Unable to enroll in Computer Architecture in classroom (says enrollment closed). Please look into it

@Arjun Sir , Are the tests scheduled here happening? If yes, can you guide me with the link. And in the classroom , are there any new assignments actively being added? Please help me out. I am not able to enrol for the most of courses as its saying 'enrolment closed'.

Tests were removed initially only. No new assignments are added to GO classroom also -- may be added for IIT interviews.

There was an error in the course settings; fixed now. Let me know if any course is not accessible.

@Arjun Enrollment in Computer Organization and Architecture course in Classroom is still closed.

Like is open rt?


 It's still closed.

Can you see now?
It's working now. Thanks a lot 😊

@Arjun Sir, while submitting assignments in GO classroom , why is it showing that assignment is submitted 1 year late, Isn't GO classroom updated for 2020?


For GATE2020 softcopy will be made available subjectwise and as per GO classroom schedule. This will include 2 versions for each subject with first for previous year GATE+TIFR questions and second for other standard questions.

GO2020 Vol 1: Questions Only

GO2020 Vol 2: Questions Only

GO2020 Vol 3: Questions Only

@Arjun sir,

These versions include GATE+TIFR. But where can I find the second version which include other standard question.

Really wanted to say Thank you for making soft copies available to everyone free of cost. I really do appreciate the effort sir. I have been using them a lot and it's very helpful for me. I know you might wonder that the year is going to end and I am appreciating the efforts now. Sorry for that sir. :)

Sir compiler design and a couple of other course are not available for enrolling..pls help
Subject courses are for last year. As of now, the relevant course is M.Tech Interview preparation.
I understand, sir but if you could make course(or atleast their material) always available it could benifit ppl like me who are willing to give gate again next year(i got 770 rank this year so not getting any good clg) and needs to start prep early
If you're having 770, you should be preparing for interviews. And all the materials you can get on subject pages. Only assignments are extra in go classroom
Ok sir...thank you for replying...and i dont think i can get any good iits as rank is above 500
If you think so you won't. Check the RA cutoffs at IITs.
ok sir..i will have a look...tysm once again
