Hi,

Assuming that you've been studying for the past year and will continue to do so with full focus and concentration, plan systematically and study hard and smart.

First, you need to revise all of your subjects. Read theory, solve questions. Strengthen your weak topics and keep hold of your strong topics. Solve as many questions as possible.

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.

Start solving previous years NEET AND AIIMS examination papers, at least two a day. Assess your mistakes, go through the theory of that specific topic, and move on. Devote the rest of the time in revising your weak topics.

At last, the most important thing is that you stay confident. Once you lose confidence, doubts arise, and that is the moment you commit mistake. So keep faith, work hard and stay confident.

Good luck.
