Hey Anu

I am assuming you are asking about physics as a part NEET or JEE exams, syllabus for boh more or less is the same. So, Physics needs utmost focus and time because it involves with theoretical concepts and numbers.

Mechanics, ElectroDynamics, Modern Physics, Heat and Thermodynamics, Optics, Simple Harmonic Motion, Waves carry a lot of weightage and these are where more number of questions come from.

Formulae are very important in physics for your preparation.

Memorise as many formulae as you can and  make formulae sheets or flash cards. Practise regularly and try various kinds of questions. Solving previous papers and mock tests to test your improvement.  for revision so as to keep the mind fresh.

this is often the question asked by most students who are eager to study but finds it difficult and time consuming when you go into it. the best way to study physics is to understand the theory and making it into practical questions, by keeping on trying the question problems. the more you keep trying and find solution to it the more you become familiar to topics, theory and finds it easy to solve problems without much difficulties. Moreover if you have a good tutor who would take you classes in an interesting way, then it would be most thrilling way to study the physics and you can score the best ranks in it...
