Every exam ViJEEta measures
One account, one engine, one set of honesty rules — four papers with genuinely different marking, kept genuinely different.
JEE Main & Advanced
Physics, Chemistry and Mathematics, every chapter weighted by its measured share of real JEE Main papers.
102 chapters with a page · 117,646 gradeable questions · readiness scored out of 300
Open JEE →NEET UG
Physics, Chemistry, Botany and Zoology — the four banks behind a /720 NEET paper.
+4 correct, −1 wrong, 0 unattempted · 180 questions · /720 · 180 minutes
94 chapters with a page · 36,527 gradeable questions · paper scored out of 720
Open NEET →Maths Olympiad (IOQM)
The Indian Olympiad Qualifier in Mathematics — 30 integer answers, no negative marking, nothing to guess at.
30 integer answers 00–99 · no negative marking · /100 · 180 minutes
5 chapters with a page · 1,256 gradeable questions · paper scored out of 100
Open IOQM →ISI B.Stat / B.Math (UGA)
The objective paper of the ISI B.Stat/B.Math admission test — the one exam that pays you for leaving a question blank.
30 MCQs · +4 correct · 0 wrong · +1 for a blank · /120 · 120 minutes
24 chapters with a page · 865 gradeable questions · paper scored out of 120
Open ISI →What is the same across all four
The engine is exam-independent: a chapter reports "—" until you have answered at least 3 questions in it, mastery is a guessing-corrected IRT true score, book work caps evidence at 0.60 and unproctored practice at 0.75, and "mastered" (≥0.80) is reachable only through tests. Each exam carries its own real total — 300, 720, 100, 120 — and nothing is ever rescaled to look better.
What only JEE has today
The headline readiness score is a weighted sum, Σ chapter_weight × mastery, so it exists only where the chapter weights have been derived — which today is JEE alone. NEET, IOQM and ISI give you per-chapter mastery on real evidence and the real marking scheme, and no single readiness number, because computing one would mean inventing the weights it stands on. The app shows no readiness band for them for the same reason.
What is deliberately different
Marking schemes are read from one file that the app grades with, so a page here cannot disagree with the product. Chapter weightage exists only for JEE, where it is derived from tagged previous-year papers — for NEET, IOQM and ISI it shows "—" until the same pass has been run. We would rather publish a blank than a plausible number.
