Preparation Strategy for NEET Chemistry 2026

We care about your performance. Preparing for NEET Chemistry is an experience in itself, and it can be confusing with so much syllabus to study. So here we offer a few tips which could make your study plan little easy if followed:

Tips:

• NCERT #1 Priority! Read NCERT textbooks carefully, especially for Inorganic Chemistry (many questions are asked directly from NCERT Book.)
• Practice numericals for Physical Chemistry! NEET loves a problem solving mind and hence the paper asks questions which require calculations. Make a habit of practicing 20-30 numericals daily, no matter what. 
• Organic Chemistry for the WIN! As scary it looks, once you understand the basics, it is really good to score a good number in exam. Focus on understanding the mechanisms and maintain flowcharts for important reactions. 
• HIGH WEIGHTAGE CHAPTERS are your ROADMAP! Very important to revise them thoroughly. 
• Solve NEET previous year papers: Practice at least the last 5 years of NEET Chemistry questions to understand exam patterns.

A good revision, prioritizing the important topics and a good practice of numericals can certainly give you the scores you desire for!
