First of all analyse the past yrs questions, you would get that ki there are some topics which are very important for jee mains and they are easy too. 1. Heat and Thermodynamics (3-4ques) 2. Modern Physics (3-4 ques) 3. Capacitors and current electricity (2-4 ques) 4. Semiconductors + communication system (1 - 2ques) 5. Optics (2-3 ques) 6. Electrostatics + Gravitation(1-2 ques) 7. Magnetism + EMI+ AC(3-4 ques, generally formula based ques) 8. SHM +Waves and Sound (2-3 ques) 9. Mechanics - till WPE your concept must be clear. In system of particles, you should have the knowledge of COM nd collision, generally questions come from collision. In Rotational Dynamics, Moment of inertia nd equilibrium part are important for jee mains. 10. Elasticity + Fluids (1-2 ques), surface tension nd viscosity are important. Bt do at last. NOTE :- Try to identify easy questions in paper nd it is not easy to get that. It depends on your practice. So practice more nd hope for the best. Be confident. #Be_better_4_better@days.#All_de@best..!!!!
