Hey Abhishek! Thanks for contacting careers 360.

Firstly I would start by saying scoring 95% in isc is not easy you need to put in a lot of dedication and hard work! Commitment to it is also very important.

You could start studying as early as possible. When the 12  standard starts and the teachers give notes and lectures learn to be as attentive as possible. Take down small notes which would help you to frame notes of your own in the future.

You could also join different tutorials that would help you prep for the final exam by providing you with mock exams papers and material.

Wish you all the best!
