Hello Enter ( Bhadana)
Well to be honest i was in the same situation when i was in my class 12. So let me tell you 5 golden rules:
1 Make NCERT your Best friend.
2 Take out question paper of 5 previous year
3 Start reading line by line ( Trust me no shortcut is there and you must give your 100%)
4 10 questions per day ( Chemistry, Physics )
5 Revise daily for 20 minutes.
