Hi,

Unit wise weightage in each of the subjects in NEET based on the previous years papers is given in the link given below -

Www.google.com/amp/s/medicine.careers360.com/articles/neet-chapter-wise-weightage-and-important-topics/amp

From the above link and from my personal experience, the easiest and the most scoring chapters are -

Physics - Thermodynamics, Electrostatics, Current electricity, EMI, Optics and electronic devices.

Chemistry - Thermodynamics, equilibrium, solutions and coordinate chemistry are scoring topics. Basics in organic chemistry are very scoring.

Biology - Diversity is scoring but students face difficulties a bit. Cell structure, human physiology are other scoring topics from 11th portion. Genetics, reproduction and ecology are scoring topics from 12th portion.

Stay focused, enhance your strengths and overcome your weak topics.

Good luck.
