What is the fastest and most efficient way to finish Physics for JEE ?

Lionel Messi was once by a journalist asked how he felt after becoming an overnight sensation at Barcelona. He was still 20 at the time. He replied. 'It took me 16 years to become an overnight sensation' The fastest and efficient way to finish Physics for JEE is to constantly work hard for two years. I'm sorry to disappoint you, but this is the only way. If you don't have that much time, I suggest you stop wasting the little time you have left asking such questions and get on with it.
