Hi harsha,

Its not maths wherein one method or formula will apply to all the problems. Physics is more conceptual based though physics cannot survive without maths Nor anyone can survive physics by rote learning. Take one topic and learn it thoroughly conceptually and try to attempt questions related to it. Concepts of physics by H.C. Verma vol 1 and vol 2 is a standard reference book recommended to every physics student here. Every physics student has to have a copy of it including me I still have it.

Further it will be helpful if you elaborate more or give an eg so that we can assist you.
