I have only few more days to give my cat exam but I'm so confused out of it

First things first, know the syllabus. And go through the previous papers to analyse and prepare a comprehensive plan and set priorities according to the importance of different topics across sections.

Customise your own study plan based on your strengths and weaknesses. Gauge your preparation from time to time by taking mock tests. Solve questions to check your levels of preparation but not to set any targets. Remember, its ok to have cheat days and relax. But make sure you have a plan and stick to it.

Dear student,
Don't panic just be relaxed
Try to solve weekly two full mock tests.
And analysis that mock very deeply for 3-4 hours.
Do SWOT analysis of every test.
Start working on week points to make into strong points.
Everything will be fine.
Best wishes
