Frequently asked questions

What is the chapter-wise weightage of NEET?

Edurack has mapped 1578 NEET questions from 2020–2026 (including Re-NEET 2026) to 98 NCERT chapters: Physics 387, Chemistry 398, Botany 405, Zoology 388. Open a subject to see every chapter ranked.

Which NEET chapters have the highest weightage?

Per subject, the top chapter is Current Electricity in Physics (34 questions); Aldehydes, Ketones and Carboxylic Acids in Chemistry (26 questions); Molecular Basis of Inheritance in Botany (47 questions); Biotechnology - Principles and Processes in Zoology (46 questions).

How should I use chapter-wise weightage for NEET preparation?

Use it to decide the order and depth of revision: start with chapters that combine high weightage and a large share of easy questions, then widen to the lower-weightage chapters. Weightage reflects past papers, so keep the whole syllabus in view.
