Hi,

This is Navdeep Rathore

Friend you are in ISC board this is a right track and getting 95% in 12  is not that tough my only advise to you is 1st of all never miss any classes and study that topic on that same day this you will do easily then you need to do is the nxt thing you need to do is solve the past years papers and modules

I hope this would help

Thankyou
