See learning Physics is all about feeling the scenario. For example you are learning Electrostatics. Then you should learn what is a Field and what is potential. You should know before memorizing the formulae that what its all about? i.e., what is field? why it is called a field and what does this field do?. So like this you should know the basics clearly and then in advanced cases you can memorize formulae.

Now memorizing a formulae is always a good strategy when you memorize it while practicing problems. SO you should practice basics problem then move to advanced one. For  example you can consider DC PANDEY/BM sharma book as a practice material, this is because this books have a summarized formulae sheet before each chapter and they strategize question level wise such as Easy, Medium and Hard. This way you will be able to build concepts as well as you will be able to clear your basics.

So this can be a good strategy for you to score good in NEET.

Now the most important chapters you must do very attentively are stated below:

• Electric Charges and Fields
• Electrostatic Potential and Capacitance
• Current Electricity
• Moving Charges and Magnetism
• Magnetism and Matter
• Electromagnetic Induction
• Alternating Current
• Electromagnetic Waves Ray Optics and Optical Instruments
• Wave Optics
• Dual Nature of Radiation and Matter
• Atoms
• Nuclei
• Semiconductor Electronics
