NEW — Test Series
Stop practicing. Start testing.
Study Notes and MCQ Practice teach you the syllabus. Test Series tells you if you're actually exam-ready — timed, negative-marked, scored the moment you submit, drawn from a fixed databank of 422,000+ real exam-style questions across every CSIR subject.
Practice teaches. Testing tells you where you stand.
Every other part of ExamCatalyst AI — Quick Concepts, Study Path, MCQ Practice — is built for learning: AI-generated on demand, ungraded, forgiving. Test Series is built for the opposite job: a fixed question bank, the same rigor as the real exam, a hard clock, and a real score.
Every question is written and reviewed in advance — never AI-improvised at attempt time. What you see is the same caliber every other test-taker sees.
A server-side clock, CSIR-style negative marking, and no do-overs mid-question — the closest you'll get to exam day without waiting for exam day.
Submit and see your score immediately — correct, wrong, and unattempted, marked exactly the way CSIR/GATE evaluators do it.
A databank built to last your whole prep
422,000+ questions across 4 subjects
Every question bank is split evenly across Basic, Intermediate, and Advanced difficulty — roughly a third each — so a test never leans too easy or too brutal, and your score genuinely reflects range, not luck of the draw.
● A pool this deep means retaking the same unit rarely repeats the same paper — every attempt draws a fresh random set from the bank.
Test your way — one lesson, one topic, or the whole syllabus
One lesson at a time — 25 questions, 30 minutes. The fastest way to check whether a topic you just studied has actually stuck.
A whole sub-domain at once (e.g. all of Organic Chemistry) — 45 questions, 60 minutes. Drawn proportionally across every lesson in that topic.
The complete subject, exam-realistic — 45 questions, 60 minutes, drawn across every unit in proportion to how often it's actually tested.
● Not every subject splits into topic-level papers — where it does, it's because that sub-domain is big enough to deserve its own full-length test, not a shortcut.
Built like the real thing
Your countdown is enforced by the server, not your browser tab — close the tab, lose your connection, or refresh mid-test, and your time keeps running exactly as it should. Reopen and you resume right where you left off, same clock, same answers.
Wrong answers cost you a fraction of a mark, exactly like the real exam — so your practice score means something. Unattempted questions are never penalized, and your score never drops below zero.
After submitting, see every question again — your answer, the correct one, and a clear explanation — so a wrong answer becomes something you actually learn from, not just a number.
A clean, focused test-taking layout that works the same way on a laptop or a phone — question and options front and center, a question-navigator always in reach, nothing to squint at.

How it works
- Sign in and open **Test Series** for your subject.
- Pick a unit, a topic paper, or Full Syllabus, and buy a pack — or use your free trial.
- Sit the test against the clock. Submit anytime, or let time run out — either way, you're scored instantly.
Attempts stack. Buy a 5-Exam Pack today and a 10-Exam Pack next month — both balances are available together, and a purchase always spends whichever pack expires soonest first, so nothing goes to waste.
Review anytime your Test Series subscription is active. Every attempt you've ever taken for a subject stays reviewable for as long as you hold any active, unexpired pack for that subject — not just the pack that funded that specific attempt. Your results are never deleted, even between packs.
