I'm a bio lang student and i'm willing to crack NEET exam. So my doubt is that is differentiation a must to study topic so as to solve physics questions for NEET?

The important topics are Optics, Ray Optics, Optical Instruments, Wave Optics, Electronic Devices, Electrostatics, Electric Charges and Fields, Thermodynamics, Electrostatic Potential, Current Electricity, Electromagnetic induction, Alternating current, Dual Nature of Radiation and Matter. Highest weightage goes to Optics at 10%. Thermodynamics, Electrostatics, Electronic devices share 9%. Current Electricity and Electromagnetic induction, Alternating current take 8%. Dual Nature of Radiation gets 6% while Motion systems of rigid particles and body and Magnetic effects of Currents, Electromgentic waves and Magentism get 5%. Work, Energy and Power take 4%, Atoms and nuclei, Oscillation and Waves, Properties of Bulk Matter, Laws of Motion and Kinematics share 3% and the rest of the topics carry 2% weightage.

And Differentiation comes under the chapter Kinematics and so it is important to concentrate on this topic. To help you with your NEET preparation, we have NEET Knockout packages that you can check at: https://learn.careers360.com/knockout-neet-may/
