Where our answers come from
Every past-paper answer on this site comes from the body that set the paper: for a CBSE board question, the marking scheme CBSE published for that exact paper — the same document its examiners marked from; for a NEET and JEE Main question, NTA’s answer key. We do not write those answers, and we do not guess them. The working we do write ourselves — our NCERT solutions, and the SolveIT solutions on some board questions — is kept apart from the official answer and described below. This page explains how each of these works, and is honest about where it stops.
Every figure above counts published questions — ones whose answer is on the site: 34,301 pages in all. They are counted from the live library, from the same index our sitemaps list, and refreshed daily.
The questions
Every past-paper question comes from a real exam paper, as the exam body printed it: CBSE’s board papers, which the board publishes after each exam, NTA’s NEET (UG) papers, and NTA’s JEE Main papers. The questions on our NCERT pages are NCERT’s own, as its books print them. Nothing here is written by us, by a tutor, or by a model. Each past-paper question page states the paper it came from: the year, the region, the set and the question number as printed — for NEET, the sitting, the booklet code and the question number; for JEE Main, the date, the shift and the question number.
CBSE answers: the board’s marking scheme
After each exam CBSE publishes the marking scheme — the official answer document. We extract each answer from the scheme belonging to that exact paper code, and store it against that question.
Most answers are read directly from the scheme’s own text. Where a scheme was published as a scan rather than text, we recover the answer from the page image and check it against the question it claims to answer. A small number of answers were repaired by hand after that check failed. Each question page shows the board’s answer, the worked solution where the scheme gives one, or both. For a writing task, the scheme lists the points an answer should cover rather than a model answer, and that is what the page shows.
What we take out, and why
A marking scheme is written for examiners, not students. Alongside the answer it carries the value-point boxes, the per-step marks, and notes like “award 1 mark if…”. We strip those out and keep the answer: the working, the derivations, the units, and both branches of every internal choice. What you read is the board’s answer without the examiner’s bookkeeping.
NEET answers: NTA’s answer key
Every NEET answer is NTA’s own answer key for that paper, taken for the booklet code the question was printed in. NTA shuffles the questions and their options between codes, so an option number means nothing without its code. Where NTA dropped a question, or accepted either of two options, the page says exactly that.
Two caveats. NTA cancelled the 3 May 2026 sitting and held the exam again on 21 June. For the cancelled paper it published no question paper and only a provisional answer key, so our copy is a scan of a printed booklet (code 11), proofread against its pages, and every answer on it is labelled as NTA’s provisional key. And NTA printed Biology as one 90-question section in 2026: the split into Botany and Zoology here is ours, following how NTA divided the same chapters in the years it printed two sections (2021–2024).
JEE Main answers: NTA’s final answer key
Every JEE Main answer is NTA’s final answer key for that shift. NTA’s key names each question and option by its own ID rather than by number, and we match on those IDs, never on the question number. Where NTA dropped a question, accepted either of two answers, or credited every answer, the page says exactly that.
NTA publishes the JEE Main paper with its questions printed as images, so the text here is our transcription of NTA’s own paper, proofread question by question against it, with its figures taken from the paper itself. Section B questions are answered with a number rather than an option: type it in, and it is checked against the key.
The working we write ourselves
NCERT publishes its textbook questions and, in most books, short answers — but no worked solutions. So the working on our NCERT pages is ours, drafted by an AI model; NCERT’s printed answer, where the book gives one, sits beside it under its own label. A solution that has not been fully checked says so, and says how far it got: whether it reaches the answer NCERT prints, whether a person has read it through yet, or that the book prints no answer to check it against. Where our working and the book disagree, the page says so rather than quietly picking a side. 7,946 NCERT textbook and Exemplar questions are on the site today, 7,931 of them with working so far.
Some board questions also have a SolveIT solution: the board’s own steps and marks, written out in full. That is our work too, drafted by an AI model. It appears under its own label, never as the board’s, and it goes live only after a person has accepted it in review.
When we don’t have the answer, we say so
260 questions in our past-paper library have no answer on the site yet; the largest groups are Class 12 Yoga (113), Class 10 English (46) and Class 12 English Core (46). Usually the reason is one of three: the board printed no answer (CBSE published no marking scheme for Class 12 Yoga before 2025, and for some English writing tasks its schemes give marking criteria but no answer); the scheme is published but not loaded yet; or the answer sits in a scan, or is a drawing, that we have not reproduced reliably. These questions say so on their page instead of being filled with a guess. They are marked noindex and left out of our sitemaps, so search engines do not list them until a real answer lands.
“Asked in 2023 & 2025” means what it says
CBSE prints three shuffled sets of each paper, so the same question often appears more than once in a single exam. That is not a repeat, and we do not count it as one. When a question page says it was asked in more than one year, it means different exam years — and the page lists each appearance so you can check.
Chapter weightage: what we counted, not what CBSE promised
On the year pages we show marks per chapter. Those are marks we counted in the papers themselves. CBSE allocates marks to units, and a unit can hold several chapters — so an official per-chapter figure does not exist, and we never present ours as one. For CBSE’s own allocation, read the syllabus on cbseacademic.nic.in.
One exam that is not like the others
The 2022 CBSE papers were the Term-II exam. CBSE split that year into two terms, so each paper covers half the syllabus in roughly half the marks, and its shape differs from every other year here. We keep them because they are real board questions, but treat them as their own thing rather than as a normal year.
Found a mistake?
Tell us and we will check it against the source document — the board’s scheme, NTA’s key or the NCERT book: hello@solveit.page. Corrections are made against the source document, never by rewriting the answer to suit an argument.
