There are 3 stages of the preparation
1.Building the concept
2.Application of concept
Application of concept should be in proper manner.Building of concept is not that much tough in physics but building proper concept in the right direction is difficult. Lots of you guys understand quickly but don't get succeeded in exam because of the aptitude in applications.
Always start with basics.
Don't run through a bundle of books instead go through one book properly line by line like in physics you can start with H.C.Verma .
Solution of the problem makes the question of no use.try to solve it yourself, give your time but if taking time again go toconept and solution and try the question again without any support.
Apply conceptual approach...
