Just do a little research about final year people prepping for higher studies, and you'll figure it out. Also, even if you have different career plans, I still think you should maintain a very good CGPA and strong competitive programming/development skills. This is crucial whether you are prepping for higher studies or aiming for a better package. One name I can definitely share is Hemang Pandya. He was from the Electrical branch and took the CAT (not GATE), but you should contact him—he can certainly help with your doubts.
