Hellp aspirant,

To give a highly competitive exam like gate, a proper revision along with  learning is  required to crack the exam

Divide the entire day according to your study plan

Make sure you revise all the important topics regarding your core subject , mathematics, Aptitude

Give some mock tests and analyse them to find out your strengths , weakness

Hope this helps you

All the best!

You should start mocks asap to check the areas where you are still lacking.
