Dear Aspirant,

See the thing is to improve anything you must identify the drawbacks, so try to find out what led to this, is it lack of knowledge of syllabus, is it exam temperament, or any thing else.

There are topics in each subject which carry good amount of weightage:

Also try to find out which topics you are facing difficulty in , which topics take more time to attempt in each subject , go through your mock test and do a self analysis and try to figure out your mistakes and not to do them again.

Try to solve as many numericals as you can and do them daily with a timer on, it will help you get comfortable with time pressure of exam.
