Hello harsh

For CPT

You can focus on economics which comparatively very easy and if you study it's chapters thoroughly you can get full marks in this part.

Don't attempt everything, only attempt in which you are sure and you know the answer as negative marking affects the overall score pretty high.

Revisions are most important part if you revise on regular basis you will learn more things for a very long, and it will help you in last days.

Before examination solve previous year question papers.they will tell you where you need to work before the exams.

Best of luck
