Here's your complete NEET Biology starter guide:

NEET Biology - Beginner's Roadmap

📊 Why Biology First? (Smart!)

  • Biology = 360 out of 720 marks (50% of total score)
  • 90 questions: 45 Botany + 45 Zoology
  • Highest return on effort compared to Physics or Chemistry

🔥 Chapter-wise Weightage (Priority Order)

📅 Suggested Study Plan (Starting from Scratch)

Phase 1 - Foundation (Months 1-3)

Start with Class 11 Biology
  1. Cell: The Unit of Life + Cell Division
  2. Biomolecules
  3. Plant Kingdom + Animal Kingdom
  4. Morphology & Anatomy of Flowering Plants
  5. Structural Organisation in Animals

Phase 2 - High-yield Chapters (Months 4-6)

Class 11 Physiology + Class 12 start
  1. Human Physiology (ALL chapters - biggest scoring block)
  2. Plant Physiology (Photosynthesis, Respiration, Plant Growth)
  3. Genetics - Principles of Inheritance & Variation
  4. Molecular Basis of Inheritance

Phase 3 - High-scoring Class 12 (Months 7-9)

  1. Reproduction (Plant + Human)
  2. Reproductive Health
  3. Evolution
  4. Ecology & Environment
  5. Biotechnology (Principles + Applications)
  6. Human Health & Disease

Phase 4 - Revision & Practice (Months 10-12)

  • Daily MCQ practice (min. 50 questions/day)
  • Full-length mock tests weekly

✅ Golden Rules for NEET Biology

  1. NCERT is your Bible - Read every line, every diagram, every table
  2. Diagrams matter - Draw and label: cell, flower, human heart, nephron, brain, etc.
  3. Never skip Assertion-Reason - ~15 of 90 questions are this type
  4. Ecology + Genetics = easiest scoring - Master these first
  5. Human Physiology = most questions - Spend maximum time here
