Dear Gautam,

To score good marks in your exam it is very important that you focus on your strength and weakness.

Try to learn from your mistakes and don't repeat them.

You should revise your syllabus as well. Focus on the topics which carries more weightage in the exam. 

You can set your time table according to your comfort so, that you can manage your studies. 

Revision and mock test series both are very important to score good marks in your exam.
