- 1 Full Biology test (90 questions)
- Revise weak chapters
How to Use NCERT Effectively
- Mark each important line
- Learn flowcharts and diagrams
- Read summary + questions at chapter end
Revision Cycle (3-Phase Method)
| Phase | Focus | Target Accuracy |
|---|---|---|
| Phase 1: Understanding | NCERT + notes | 60-70% |
| Phase 2: Reinforcement | PYQs + mock tests | 80-90% |
| Phase 3: Mastery | Full syllabus tests + flashcards | 95-100% |
Common Mistakes Students Make
- Relying on bulky guides instead of the NCERT
- Memorising examples rather than understanding topics
- Ignoring diagrams, tables, and summary boxes
- Not solving PYQs consistently
- No weekly revision cycle
With the right strategy, discipline, and pattern-based preparation, Biology can become your highest scoring and most predictable subject in NEET 2026.
