Which Class 12 chapters have highest NEET weightage?

Genetics & Evolution (18%) is the most important unit, followed by Reproduction (12%) and Ecology (12%). The chapter "Principles of Inheritance and Variation" alone can have 8-10 questions in NEET.

How to prepare Class 12 Biology along with boards?

Read NCERT thoroughly for both boards and NEET. Focus on diagrams, flowcharts, and definitions. Practice MCQs alongside board preparation. Topics like Genetics, Reproduction, and Ecology are equally important for both exams.

Can I skip some chapters in Class 12 for NEET?

No chapter should be skipped as NEET asks questions from every chapter. However, prioritize high-weightage chapters like Genetics (10 Qs), Human Reproduction (6 Qs), and Ecosystem (5 Qs) while ensuring basic coverage of all topics.
