Short term coaching

short term coaching are only for revison purpose and they definately benefit you. You can join the course.

Agreed with Raghavender..

I think short term coaching is not worth trying, I  will suggest you to join for subjects(to the max 3) in which coaching is required & you thing you are not comfortable with and the rest can be done through self study. As the time left is very less you need to study smartly and rigourously
