CSIR NET Syllabus and Marking Scheme for Every Subject

CSIR NET syllabus at a glance: one paper, three parts

Unlike most recruitment tests, nothing is split into rounds. You take one objective paper on one day, and the result alone decides whether you qualify. Inside that paper the three parts test different things:

• Part A: general aptitude, the same style of questions for all five subjects.
• Part B: conventional questions from the core of your subject, close to what you studied in your MSc.
• Part C: longer, application based questions where you must apply concepts, read data or solve a multi step problem.

You do not have to answer every question. Each part gives you more questions than you are allowed to attempt, so choosing which ones to leave is a real skill. If you answer more than the permitted number, only the first ones up to the limit are evaluated.

CSIR NET marking scheme subject by subject

Questions, attempt limits and marks per question differ by subject, which is why the CSIR NET marking scheme confuses many first time candidates. The table below follows the pattern reported for the latest cycle.

In every subject Part A carries 30 marks. Part C is worth 100 marks in all subjects except Mathematical Sciences, where Part B carries 75 and Part C 95. In the maths Part C a single question may carry several right answers, and credit comes only when every right answer is marked, which is why there is no negative marking there.

Part A: general aptitude topics

Part A is the same short section for everyone and is the easiest place to pick up marks. Its listed topics are:

• Logical reasoning and puzzles
• Graphical analysis and reading charts
• Analytical and numerical ability, such as arithmetic, percentages and simple calculations
• Quantitative comparison
• Series formation
• Elementary scientific reasoning and data interpretation

Fifteen correct answers out of twenty give you 30 marks, so steady practice of ten to fifteen questions a day for a few months is usually enough.

Parts B and C: the five subject syllabi

The subject syllabus is shared by Part B and Part C; the difference lies in the depth of the questions. Below is a broad outline of each.

Chemical Sciences

Inorganic chemistry (periodic properties, bonding, coordination compounds, organometallics, bioinorganic chemistry, spectroscopy of inorganic compounds), physical chemistry (quantum chemistry, thermodynamics, kinetics, electrochemistry, spectroscopy, solid state) and organic chemistry (stereochemistry, reaction mechanisms, synthesis, pericyclic reactions, natural products and structure determination), plus interdisciplinary topics such as environmental, polymer and nano chemistry.

Life Sciences and Biotechnology

The long running life sciences syllabus is organised into 13 units: molecules and their interactions, cellular organisation, fundamental processes, cell communication and signalling, developmental biology, plant physiology, animal physiology, inheritance biology, diversity of life forms, ecological principles, evolution and behaviour, applied biology, and methods in biology. With the merger of the biotechnology eligibility test into CSIR NET, a revised combined syllabus is part of the information bulletin; our life science page walks through each unit.

Physical Sciences

Part B: mathematical methods of physics, classical mechanics, electromagnetic theory, quantum mechanics, thermodynamics and statistical physics, electronics and experimental methods. Part C goes deeper into these and adds atomic and molecular physics, condensed matter physics, and nuclear and particle physics.

Mathematical Sciences

Four units: analysis and linear algebra; complex analysis, algebra and topology; ordinary and partial differential equations, numerical analysis, calculus of variations, integral equations and classical mechanics; and statistics with probability, inference, sampling, design of experiments and operations research.

Earth, Atmospheric, Ocean and Planetary Sciences

Part B tests general earth science: the earth and solar system, earth materials and processes, the atmosphere and oceans, and environmental earth science. Part C lets you pick from geology, physical geography, geophysics, meteorology and ocean sciences, which is why this subject has 80 Part C questions to choose 25 from.

CSIR NET new syllabus: what changed in life sciences

Searches for the CSIR NET new syllabus mostly come from life sciences candidates. The Department of Biotechnology's separate biotechnology eligibility test has been merged into CSIR NET, so the paper is now listed as Life Sciences and Biotechnology, and DBT fellowships are filled through this joint test. The reported pattern for the merged paper keeps 145 questions with 75 to attempt for 200 marks.

What has changed is the content. A revised syllabus that folds biotechnology topics into the classic biology units is printed in the bulletin. Earlier life sciences question banks still help, but they do not cover everything.

Where to focus your preparation

Because Part C carries half the marks, your rank depends on how many of its questions you can solve accurately. A few points that follow from the pattern:

• Physics: with only 20 attempts in each of Parts B and C, every question is worth 3.5 or 5 marks. Accuracy matters more than speed.
• Chemistry and life sciences: Part C allows 25 out of 60 or 75, so wide coverage gives you more questions to choose from.
• Maths: no penalty in Part C, but partial marking does not exist. Practise multi option questions until you check every option.
• Earth sciences: master the Part C stream closest to your MSc, but keep a second one ready.

A six month study plan for CSIR NET

1. Months 1 and 2: read the official syllabus line by line and revise your MSc notes unit by unit. Make one page summaries of formulas and reactions.
2. Months 3 and 4: move to problem solving at Part C level. Solve questions from previous papers available on the NTA and CSIR HRDG websites, unit by unit.
3. Month 5: full 3 hour mock papers once a week, with careful analysis of which questions you attempted and which you should have left.
4. Month 6: revision of weak units, Part A speed work and two more full mocks.

For books, rely on the standard university textbooks you used in your degree. If you are also weighing the humanities route, compare this with the UGC NET syllabus, which has no negative marking.

Eligibility and next steps

You need an MSc or equivalent degree, an integrated BS MS, a four year BS, BE, BTech, BPharma or MBBS, with the minimum percentage set in the bulletin (55 percent for the unreserved and EWS groups, 50 percent for some reserved categories, as reported). For JRF the upper age limit is 30 years which is relaxed for SC, ST, OBC NCL, PwD, third gender and women applicants, by amounts the bulletin sets; candidates seeking only lectureship or PhD admission face no upper age cap. The full rules are on the CSIR NET eligibility page, and the marks you need to target are on the CSIR NET cut off page.
