i am in 11th std. till 10th i just used to love maths(i also scored 98%in maths in boards. n 95% aggregate)
but now i am in a terrible situation. i just cant handle this subject and it is getting out of my grip.
also i dont find my maths teacher of any help to me. though he has expertise in the subject but he just rushes to complete the course. i dont like his method of teaching at all as he is ignoring the quality and concentrating only on quantity. hardly anything goes into my head. i feel his lectures are a waste of time.
i feel myself out of the competition as my biggest strength has turned into my biggest weakness.

please help me!!!
also suggest some books which will help me regain my confidence and enable me to get back in the competition.
