How to Prepare NEET Biology Questions to Score High

To score well in NEET Biology, aspirants need to study smart. Because of the lengthy syllabus, using the time effectively is important. So, focusing more on chapters that have high weightage, like Molecular Basis of Inheritance, Animal Kingdom, Cell Cycle, Biomolecules, and Biotechnology, is a good way to cover the syllabus.

• Start by solving chapter-wise NEET questions with answers after reading each NCERT chapter. For example, after reading "Molecular Basis of Inheritance," try to solve at least 30 to 40 NEET questions on DNA structure, replication, and genetic code.

• In chapters like Animal Kingdom and Plant Kingdom, classification-based questions are generally asked. So, create a comparison table for different groups and keep solving match-the-following and statement-based MCQs regularly.

• Chapters like Cell Cycle and Cell Division and Human Reproduction need a clear understanding of diagrams and sequences. So, practice diagram-based questions, and revise processes like meiosis, fertilization, and gamete formation step-by-step.

• In Biotechnology, focus on basic tools like plasmids, restriction enzymes, and cloning. NEET asks application-based questions, so revise definitions with examples and solve assertion-reason-type questions.

• Also, solve previous year's topic-wise NEET biology questions with solutions. For example, collect all PYQs from “Photosynthesis in Higher Plants” and solve them together.

• Also, note down the tough questions and come back to them during revision. Keep a notebook of such questions and short tricks to solve them. This helps a lot before the final exam.
