Test Manthan really helped me because PsiGenei's analytical and advanced questions felt different from the usual practice. I felt some questions in the exam were very similar to what I had practiced.

Regular question practice helped me secure AIR 75 in CSIR-NET JRF on my first attempt. I recommend Test Manthan for structured, exam-oriented practice alongside your preparation.

Questions CSIR NET students ask

What's in the CSIR NET test series?

Full mocks in the real Part A, B and C pattern, unit tests for each of the 14 units and Part A, and part tests that give you Part A, B or C on its own at its real length and marking. New ones are added every week until the exam. After each test you see your score by part, subject and topic.

Does it follow the pattern of the next exam?

Yes. The mocks follow the pattern in the latest official notice for December 2026. If the pattern changes, the mocks change with it.

Is the test series in monthly plans?

No. The test series comes with annual plans only: Manthan Elite: CSIR NET, or Manthan Elite.

What is the difference between the two plans?

Nothing, except the exams. Manthan Elite: CSIR NET gives you everything in Elite for CSIR NET only. Elite gives you the same for all 7 exams.

Can I practice Part A, B and C separately?

Yes. Choose a part when you create a test. Parts A and B are marked +2 and −0.5, Part C +4 and −1, as in the exam.

Which subjects can I test?

All 18 subjects of Parts B and C, and General Aptitude for Part A.

Do free papers use my 5 free tests?

No. Past papers and topic sets on the free practice page don't count. Only tests you create count.

Does my plan renew automatically?

No. Payment is one-time. Nothing is charged again unless you buy again.

Are these the real CSIR NET papers?

Yes. Each paper has the questions as they were asked in that exam, in the same parts and order.

Do I need an account?

Yes, a free one. Sign up with Google or email. No card needed.

Can I download the papers?

Yes. Each paper's PDF is in our free downloads. Choose "Get the PDF" on a paper.

How do I practice a topic that isn't in the free sets?

Pick its subject under "Every other topic". It opens Test Manthan with that subject chosen.

Are the papers timed and marked like the real exam?

Yes. 3 hours, Parts A, B and C, the same "attempt any" rules and the same negative marking.
