No account needed. Sign in only if you want your progress kept across devices.

02 · The source

Every paper, taken apart.

789 questions from CISCE’s board papers, specimen papers and item bank. Each one keeps its year, its paper and its question number, and links back to the PDF on cisce.org wherever CISCE has published one.

03 · Filed

33 chapters. Nothing the syllabus dropped.

Each column is a chapter of the 2027 syllabus. The taller the column, the more marks CISCE has spent on that chapter, on average, per paper.

04 · Practise

Five questions, five chapters.

Tick the chapters you want and a set draws from every one of them. MCQs are checked at once against a verified key. Written answers are shown, never scored.

05 · The name

Sublevo: I lift from beneath.

That is what the word means in Latin. 2,500 questions and 241 notes articles go underneath, a chapter at a time. The way you study is what rises.

What you can do here

Practise by chapter

Tick the chapters you want, choose how many questions, and start. A set draws from every chapter you ticked, so five questions from five chapters is five chapters, not one.

Open Practise

Sit a whole paper

Work through a past board paper or a specimen paper from the first question to the last, in its own sections, with the marks CISCE gave each question.

See where you stand

Progress sets what you have read against what you have answered. A chapter read but never answered is untested; a chapter answered but never read is guessing.

Where the marks have been

The three chapters in each subject that CISCE has spent the most marks on, as an average per paper over the board papers we hold. Marks are per paper: Physics 70, Chemistry 70, Maths 80. It is a ranking aid, not a forecast.

  1. Ray Optics11.6 marks
  2. Magnetism9.0 marks
  3. Electrostatics8.2 marks

CHE Chemistry

  1. Solutions9.0 marks
  2. Alcohols, Phenols and Ethers8.5 marks
  3. Electrochemistry8.3 marks

MAT Maths

  1. Probability13.0 marks
  2. Integrals10.0 marks
  3. Determinants8.0 marks

What we hold ourselves to

  • Every question says where it came from. An official question names its year, paper and question number, and links to the PDF on cisce.org wherever CISCE has published one. Anything the board did not write is labelled Practice, on the card, before you answer.
  • You never mark yourself. MCQs are checked at once against a verified key. Written questions show the answer and are not scored, because a mark you gave yourself tells you very little.
  • Nothing is passed off as the board’s. Where CISCE has not yet published an answer, the card says so; if it shows a draft answer in the meantime, the draft is labelled as AI-generated and not from CISCE, and it is never used to mark you. Where a question came without marks, it says “marks not stated”.
  • Sublevo is independent. It is not affiliated with, endorsed by or approved by CISCE. Where the content comes from.
