************* Hey ppl!!!!!! **********
This post is to share your basic concepts of physic, chemistry and maths. 
Please do share concepts you know which you've mastered, and other people will help you in return!!!
So here we go!!!
PS: Please post something!!! I studied virtually nothing in the past two years and I'll just scrape through XII.
But everyone's saying that AIEEE success is based on how many concepts you know, not how many hours youv'e studied.
So please make a summary of formulae,concepts or something and help this poor kid!
