ToggleNEET Previous Year Question Paper - Biology
Biology plays the most decisive role in cracking NEET because it carries 50% weightage of the paper. Students who consistently practice from the NEET previous year question paper of Biology understand not only the exam pattern but also the depth of concepts required. Every year, almost 60–70% of Biology questions are directly linked to NCERT lines, and PYQs make this clarity even stronger.
Chapter-wise Weightage in Biology (Based on NEET Previous Year Question Paper Analysis)
Biology contributes 90 questions out of 180 in NEET, making it the deciding subject. Past year analysis clearly shows that some chapters are repeatedly targeted by NTA. Here is a broad chapter-wise trend:
Class 11 Biology
•Diversity of the Living World – 8–10 questions
•Structural Organisation in Animals and Plants – 6–7 questions
•Cell Structure and Function – 6–8 questions
•Plant Physiology – 8–10 questions
•Human Physiology – 10–12 questions
Class 12 Biology
•Reproduction – 8–10 questions
•Genetics and Evolution – 10–12 questions
•Biology in Human Welfare – 4–5 questions
•Biotechnology and Its Applications – 5–6 questions
•Ecology and Environment – 8–10 questions
Note-
- Human Physiology and Genetics & Evolution together carry almost 20–25% of the Biology marks.
- Ecology is a consistent scoring area, with direct NCERT-based questions.
- Reproduction and Plant Physiology chapters also frequently appear in the NEET previous year question paper.
- Biotechnology, though small, always contributes sure-shot questions.
- Diversity of the Living World often has straightforward factual questions, easy to score if revised properly.
Trends Analysis of NEET Biology Questions
When we look at the NEET previous year question paper, clear patterns emerge that help aspirants plan their preparation smartly. Biology has always been the most crucial section, but the weightage distribution and difficulty level have shown subtle changes over the years.
1. NCERT-Centric Questions
Over 80–85% of Biology questions come directly from NCERT lines. NTA has tightened its focus on NCERT-based facts, making line-by-line study non-negotiable.
2. Increasing Emphasis on Human Physiology and Genetics
In the last 5 years, Human Physiology and Genetics & Evolution consistently make up 20–25% of Biology marks. This shows a stable trend, meaning students cannot afford to skip or under-prepare these chapters.
3. Ecology and Environment Gaining Weight
Ecology questions have increased, with 8–10 questions almost every year. This aligns with NTA’s push towards environmental awareness and sustainable development topics.
4. Repeated Question Types
Many PYQs appear in re-framed or twisted versions. For example, Genetics problems (blood group, inheritance patterns) often repeat with just different data. Students solving NEET previous year question paper gain the edge to spot these.
5. Difficulty Level Trend
- Earlier papers (before 2020) had moderate Biology sections.
- From 2020–2022, papers shifted towards more direct NCERT factual questions.
- In 2023–2024, Biology remained NCERT-based but demanded more application of concepts, especially in Genetics, Physiology, and Ecology.
