How to read Sublevo.

Every question says where it came from, above the question itself, before you reveal anything.

• Official CISCE: transcribed from a CISCE board paper, specimen paper or the competency item bank. It carries the exam year, the paper, the question number, the marks and a link to the source PDF so you can check us. There are 789 of these.
• Practice: never written by the board. Each one says whether it was written for Sublevo with AI assistance or adapted from third-party coaching material (the publisher of those was not recorded, and the card says so). Useful for volume and drill. There are 1,713 of these, and each one says so on its face. We will never pass one off as a board question, and a practice answer says it has not been checked against a CISCE marking scheme.

Because there genuinely is no answer yet. CISCE publishes a paper first and its marking scheme months later, so the 2026 board questions are here with no official answer behind them: 104 questions today.

We do not write our own solution and print it as if it were the board’s. You can still read and think about the question; nothing is marked, and nothing is counted as wrong. When CISCE publishes the answers, they appear.

The figure is the average marks CISCE has spent on that chapter per paper, over the papers in our bank for the subject, counting official questions only. It is a ranking aid, not a forecast: it says nothing about what the next paper will contain. Marks are per paper, never per year: Physics 70, Chemistry 70, Maths 80.

Practice questions often come without marks. We never guess a mark, so the card says so. A set’s summary adds up only the marks that are stated, and says how many questions have none.

Your record of what you have answered and which articles you have read is kept on this device from your first question. If you sign in, it is sent to your account; when you sign out, the copy on this device is removed.

If you study without signing in, the record lives only in this browser, and clearing the browser’s data for this site removes it. Sign in and it is kept on your account too, so a second device picks up where you left off.

Sublevo follows the ISC 2027 syllabus: 33 chapters across the three subjects, and it leaves out what that syllabus dropped, because a candidate for the 2027 paper has no reason to revise a topic the board will not set. If a chapter your school taught is missing, it is almost certainly off the syllabus. If you think that is wrong, tell us and we will check it against the CISCE PDF.

The board questions in Sublevo are the real ones. Their text, the official answers and the examiners’ comments are reproduced from papers published by the Council for the Indian School Certificate Examinations (CISCE), and that material is CISCE’s copyright, not ours. Every official question names the paper it came from (year, paper, question number) and links to the PDF on cisce.org, so you can always read it at source.

Sublevo is an independent study tool. It is not affiliated with, endorsed by, or approved by CISCE, and nothing here is an official publication. What we add is our own: the chapter notes, the marks-per-paper analysis and which questions sit together.

Two limits we hold ourselves to. Questions not written by the board are always labelled Practice and never carry an exam year, a paper or a link to a CISCE document, so nothing labelled Practice can pass itself off as a board question. And we do not copy diagrams from CISCE papers: where a board question has a figure, we link to the original paper, and where we have redrawn it ourselves the drawing says so and names the page it was drawn from.
