Can I study for Cs gate exam, if Im in mechanical engineering first year?

Kamal Kishor Chaurasiya 9th Aug, 2020

Hi Aditya,

Yes you can appear in GATE examination with CSE paper if you have Mechanical engineering degree.

The basic academic qualification required for GATE is that candidates must have passed graduation in engineering/technology or Master’s degree in any relevant science subject. Candidates in pre-final or finaly year of their qualifying degree also eligible to appear for GATE. This year the third year students can also write GATE examination.

If you are Mechanical engineering candidate and would like to write GATE with CSE paper then you can give GATE but it will not be beneficial for you in my view. Rest is upto you. You have to write and prepare for GATE.

For more information please check the link below: https://www.google.com/amp/s/engineering.careers360.com/articles/gate-eligibility-criteria/amp

All the best.

Hey there, Can anyone tell me , where can I get free coaching lectures with material and mock tests for GATE preparation ....??and,( tech tub, gate overflow platforms are free??? please answer me....

rajaman9300 Student Expert 8th Aug, 2020

I don't understand why do you want for free. Don't you think that the professors or the teachers also need money to run their family or they also need money for daily uses. It is better you should have asked for a nominal rate course rather than free.

If you are from Electrical Engineering or Mechanical background then i would suggest GATE Academy or Xerique Education. You can also watch their you tube videos if you don't want to spend a penny on any of their premium courses.

All the best!!
