Hello,

Class 11th exam is not entrance and don't get nervous. You have to score well. Try to study and practice more. If you do you will get good marks. Passing percentage might be 35. but why to look for minimum. try to study. this is not such a bad thing. Study and do it in more interesting by drawing your understanding. visuals are more easy to remember. the most important thing is practice. if you don't practice then no one can help you. It is boring and difficult but your career will be at risk and it is not that bore. there are teachers to help you. the only thing you have to start learning. If you have any doubt then you can ask them to help you clear it or solve it for you.

Hope it helps!
