What Is CSIR NET? Routes, Eligibility and Marks for Maths

CSIR NET, the Joint CSIR-UGC National Eligibility Test, is conducted by the National Testing Agency (NTA) for CSIR. It decides whether Indian nationals are eligible for a Junior Research Fellowship (JRF), an Assistant Professor appointment, or PhD admission, in one of three combinations (about the Joint CSIR-UGC NET).

The rules that follow from the table:

• A JRF holder is admitted to a PhD by interview.
• For categories 2 and 3, the NET score counts for 70% of PhD admission and the university interview for 30%. The score is valid for one year for this purpose.
• The Assistant Professor qualifying certificate has no end date.
• As of the December 2026 bulletin, the JRF stipend is ₹37,000 a month for two years, plus a ₹20,000 yearly contingency grant. It rises to ₹42,000 a month from the third year as a Senior Research Fellow, after a progress review and if you are registered for a PhD (bulletin, section 1.8).

The outcomes are not evenly spread. For June 2025, Careers360 reported six qualifier groups across all five science subjects:

Our sums: the six groups add up to 15,002. The four JRF groups total 2,884, about 19%. Assistant Professor with PhD admission is 2,886, about 19%. PhD admission only is 9,232, about 62%. Maths-only counts are not in that report. For most qualifiers the exam is a route into a PhD, and the fellowship is the rarer outcome.

As of the December 2026 bulletin, you can apply with a master's degree at 55% marks (50% for OBC non-creamy layer, SC, ST, PwD and third-gender candidates), or while enrolled in a master's programme in any year. Our eligibility guide covers each category in detail.

As of 10 October 2026, applications for the December 2026 session are open until 5 November 2026, and the exam is scheduled for 19, 22 and 27 December 2026 (bulletin, dates at a glance). Our application form guide walks through the steps, and our exam date page tracks the schedule.

The terms used in the table:

• EWS: Economically Weaker Sections.
• OBC-NCL: Other Backward Classes, non-creamy layer.
• SC: Scheduled Caste.
• ST: Scheduled Tribe.
• PwD: persons with disabilities.

Age matters only for the JRF. You must be no more than 30 on the first day of the month in which the exam concludes. Up to five years' relaxation is available for OBC-NCL, SC, ST, PwD and third-gender candidates and for women, and also for research experience and armed forces service. The total relaxation cannot exceed five years. There is no upper age limit for Assistant Professor or PhD admission only (bulletin, section 2.1.2).

The Mathematical Sciences paper (subject code 704) has 120 questions, but you may attempt only 60, and it is marked out of 200. It is a three-hour computer-based test with no break between parts (bulletin, section 3.2).

Check: 15 × 2 = 30, 25 × 3 = 75 and 20 × 4.75 = 95, which total 200.

Two rules catch people out:

• Answering more than the limit. If you answer more than 15, 25 or 20 questions in a part, only the first 15, 25 and 20 are marked. Extra answers earn nothing and use time you need elsewhere.
• Part C works differently. A question can have one or more correct options, and you get credit only if you identify all of them. Wrong answers carry no penalty.

Parts A and B have one correct option per question, and a quarter of the marks is deducted for a wrong answer.

No. The pass mark only makes you eligible to qualify, and your category's JRF cut-off decides the fellowship. For General candidates in Mathematical Sciences, the JRF cut-off sat 20 marks above the pass mark in June 2026 and about 41 marks above it in June 2025. There is no separate cut-off for Parts A, B and C. Cumulative marks decide the merit list, and the results committee sets how many candidates fall into each category. The minimum is 33% for General, EWS and OBC, and 25% for SC, ST and PwD (bulletin, section 11.3).

As of 10 October 2026, the latest published session is June 2026. Marks are our conversion: percentage × 200. The percentages are as reported on Adda247 (June 2026) and Careers360 (June 2025).

Cut-offs move between sessions. The General line fell by 20.75 marks between June 2025 and June 2026, and the SC line by 10.25. Our cut-off guide tracks them.

Two mistakes follow from this:

• Aiming at the pass mark. A student who plans for 66 marks may qualify and still miss the fellowship line.
• Neglecting Part C. Part C is the largest block of marks and has no penalty. Our recommendation is to attempt all 20 questions you are allowed there. Spend any time you save on Parts A and B on the Part C questions you can partly solve.

Estimate your CSIR NET maths marks as 2 × A correct − 0.5 × A wrong + 3 × B correct − 0.75 × B wrong + 4.75 × C correct, then compare the total with your category's JRF cut-off in the table above. The formula is our working from the bulletin's marking scheme, not an official calculator. Run it on your last full-length mock paper.

Read the total against these lines for your own category:

1. Below your pass mark (66 or 50): fixing wrong answers in Parts A and B is the fastest gain.
2. At or above the pass mark but below your category's JRF cut-off: you are in range to qualify, and the fellowship is not yet secured.
3. At or above your category's JRF cut-off: the line moves, so as a rule of thumb, aim for 10 to 15 marks over the latest line. That is our rule of thumb, based on the moves of 10.25 and 20.75 marks between the last two sessions.

The worked example scores 118.75. A General candidate with that total would be 32.75 marks over the June 2026 line and 12 marks over the June 2025 line. It uses only 10 correct Part C answers, so Part C is where a stronger result would come from.

SBTech Math offers live online classes and recorded courses for CSIR-NET, with PDF notes, assignments, previous-year-question discussion, mock tests and analytics. We also run a mathematics test series, including the Core Concept Diagnostic test series. SB Sir designs all of our test series and conceptual tests.

SB Sir teaches Pure Mathematics, Eshita Mam teaches Applied Mathematics, and Vivek Sir teaches Abstract Algebra and Real Analysis. Our app dashboard tracks course completion and test scores. Our courses are made for BSc students, MSc students, graduates and working learners.

You can start without paying. Our free mathematics study content includes TJK 9.0, demo classes, a PDF Drive, notes and previous-year questions.
