CSIR NET 2026 — Paper Structure
The single paper is divided into three parts:
| Part | Focus | Questions | Marks | Negative Marking |
|---|---|---|---|---|
| Part A | General aptitude — reasoning, comprehension, numerical ability | ~20 | ~30 | −0.5 per wrong |
| Part B | Subject-specific — direct concept MCQs | ~40–50 | ~70–80 | −0.5 per wrong |
| Part C | Higher-order reasoning — application and analysis | ~30–40 | ~80–100 | −1 per wrong |
Part C is the most discriminating — it determines your rank and JRF eligibility. Most toppers score 80%+ in Part C.

JRF vs Lectureship — What's the Difference?
| Aspect | JRF | Lectureship Only (LS) |
|---|---|---|
| Fellowship | ₹31,000/month (JRF) → ₹35,000/month (SRF after 2 years) | None |
| Total Fellowship Value | ~₹19–22 lakh over 5 years | — |
| Research | Eligible for full-time PhD with fellowship | Eligible for PhD (with institute support) |
| Teaching | Eligible for Assistant Professor | Eligible for Assistant Professor |
| Age Limit | Maximum 30 years (with reserved-category relaxation) | No upper age limit |
| Cutoff | Higher | Lower |
CSIR NET 2026 — Indicative Cutoff
CSIR NET publishes category-wise cutoffs for JRF and Lectureship separately:
| Subject | JRF Cutoff (Gen, Approx.) | Lectureship Cutoff (Gen, Approx.) |
|---|---|---|
| Chemical Sciences | ~110–130 / 200 | ~95–110 |
| Life Sciences | ~115–135 | ~100–115 |
| Mathematical Sciences | ~100–120 | ~85–100 |
| Physical Sciences | ~110–130 | ~95–110 |
| Earth Sciences | ~100–120 | ~85–100 |
Cutoffs shift each year based on paper difficulty and the candidate pool. OBC/SC/ST/PwD cutoffs are lower.
CSIR NET 2026 — 6-Month Preparation Plan
- Months 1–2: Subject Coverage — Read standard PG textbooks (Physical Chemistry by Atkins, Molecular Biology by Lodish, etc.) for your subject. Cover each unit methodically. Make concise notes.
- Month 3: Part A Practice — Reasoning, quantitative aptitude, and graph/data interpretation. Solve RS Aggarwal or Arun Sharma for aptitude.
- Months 3–4: Previous Year Papers — Solve at least the last 10 years of CSIR NET papers. Time yourself strictly.
- Month 5: Mock Tests — 2–3 full-length mocks per week. Identify weak units and revise.
- Month 6: Revision + Weak Areas — Revise short notes daily. Re-solve the most-missed questions.
Best Books for CSIR NET 2026
Subject-specific books vary, but commonly recommended references include:
- Chemical Sciences: Physical Chemistry (Atkins), Organic Chemistry (Morrison & Boyd, Clayden), Inorganic Chemistry (Lee, Greenwood)
- Life Sciences: Molecular Biology (Lodish), Genetics (Griffiths), Biochemistry (Berg, Stryer)
- Mathematical Sciences: Topology (Munkres), Linear Algebra (Hoffman & Kunze), Real Analysis (Rudin)
- Physical Sciences: Classical Mechanics (Goldstein), Quantum Mechanics (Griffiths), Statistical Mechanics (Pathria)
- Earth Sciences: Structural Geology (Davis), Geochemistry (Faure), Atmospheric Science (Wallace & Hobbs)
Pair books with an online question bank (IndiaBix, Testbook, or specific CSIR-NET platforms).
CSIR NET — Common Pitfalls to Avoid
- Ignoring Part A. Many candidates focus only on B and C and lose easy marks in General Aptitude. Part A carries 30+ marks and is fully preparation-based.
- Rote memorisation. CSIR NET Part C tests reasoning, not recall. Memorising formulas without understanding when to apply them fails.
- Skipping previous-year papers. Repeats and pattern recognition are common — at least 10 years of papers should be solved.
- No mock tests. The 3-hour timer is unforgiving — practising in timed conditions is essential.
- Over-focus on rare topics. 80% of marks come from 20% of topics — prioritise high-yield units.
Quick Statistics — CSIR NET Trends
| Metric | Recent Cycle |
|---|---|
| Total Applicants | ~3–4 lakh across all 5 subjects |
| Appeared | ~70–80% of applicants |
| JRF Awarded | ~3,000–4,000 across all subjects |
| Lectureship Awarded | ~30,000–40,000 |
| Overall Selecture Rate | ~10–12% |
Competition is highest in Life Sciences and Chemical Sciences, moderate in Mathematical and Physical Sciences, and relatively lower in Earth Sciences.
