Hi friends this is my first post on PF. I see their is some undiscovered resource in Forum. I am appearing for exams like BIT-SAT, AIEEE and Advanced Placement and A-Levels. I need those books which can make concepts clear in Physics from scratch or at intermediate level. And also for Maths which include Inverse Trignometric Functions and the most important Calculus. You can also suggest me some Pre-Calculus resources.I need this resource so that I can master the topic in minimum time as possible. I hope this would help me. I have the following books available right now for physics. 1. I E Irodov 2. Fundamentals of Physics by Resnick, Halliday and Walkar. I uses these two books to strengthen by concepts and problem solving ability.
