Practise topical past papers. Revise with a plan that adapts.

A free one-stop shop for exam revision for A Level, IGCSE, IB and SPM students. Most subjects arrive with your exam board's syllabus already loaded. Then everything is in one place: today's plan, a review board, past papers from nine exam boards, past-paper questions you can search by word, chapter or difficulty, a mock exam builder, self-marking multiple-choice practice, syllabus goals, an exam planner, a study log, grade targets, flashcards, tasks, notes, a calendar and your full history. Teachers get classes, tests, worksheets and syllabus plans.

Nothing. Every account is free, with no limits on subjects, topics or papers.

Cambridge International AS & A Level and IGCSE, the IB Diploma Programme, Edexcel International A Level and International GCSE, the AQA, OCR and Edexcel A levels, all 42 College Board AP courses, the SAT and the ACT, and all 95 SPM subjects. You can also add any subject of your own and paste or import its syllabus.

Yes. Each question is cut from a paper the exam board published and filed under the chapter it tests, with its part of the mark scheme where one exists. Multiple-choice questions show the answer letter. SPM papers have no schemes. Questions open when you sign in; the public pages only list what is there.

Cambridge IGCSE, O Level and AS & A Level subjects such as Physics 9702, Chemistry 0620 and Mathematics 9709; Pearson Edexcel International GCSE and International A Level; AQA and OCR GCSE and A Level; the IB Diploma; and SPM Mathematics, Additional Mathematics, Physics, Chemistry, Biology and Science. Every board, subject and chapter is listed on the topical pages, free to browse without an account.

Not to browse. The topical pages list every board, subject and chapter. To open questions and mark schemes, save them, build a mock or track your syllabus, you need a free account.

From your syllabus. Each point you track has a status, and the status sets how soon it comes back: 3 days at Learning, up to 14 at Exam Ready, sooner if you rate it hard. Each review that goes well doubles the gap, up to 60 days, and choosing Learning starts it over. Today’s plan takes what is due, puts the topics of an exam within 45 days first, keeps a session for new material and fits the rest to the minutes you have. There is no guesswork: the same answers always give the same dates.

Pick a syllabus, the chapters you have covered and a length: quick, standard, a full paper or your own. Where questions are rated, pick Easy, Medium or Hard too. Momentum draws the questions. Sit the paper timed, untimed or open book, then mark it against the schemes. Save the paper and scheme as PDFs, with answer space under each question if you want it.

From the exam board’s examiner report. An AI model reads what the report says about each question and rates it 1 to 5: questions most candidates got right are Easy, ones very few got right are Hard. With no report, the rating is estimated from the question and its mark scheme, and labelled as such. Most Cambridge A Level and IGCSE syllabuses are rated, plus some from Pearson Edexcel and OCR.

Not yet. Automatic marking for written answers is what we are building next. Today, multiple-choice practice and teachers’ multiple-choice tests mark themselves. For written questions, the mark scheme sits under each one: enter your marks and Momentum totals the score and shows which chapters lost marks.

Yes. Sign up as a teacher, create a class and share its join link. Set self-marking multiple-choice tests, or set any mock you build as a worksheet that students do on paper and hand in as photos. You mark it in Momentum and return it with feedback. Each class gets a syllabus plan, and printed papers carry your school’s name and logo. Schools can also start with a three-month pilot.

Not like a textbook: there are no notes or videos. It has past papers from Cambridge, Edexcel, AQA, OCR, IB and SPM, filed by chapter and mostly with mark schemes, to practise a topic or build a timed mock. Keep your textbook, slides or revision site. Momentum tells you which to open tonight and what your last paper got wrong.

Yes. Momentum is a web app that works in any modern browser on a phone, tablet or laptop. There is nothing to install.

Yes. Every screen is in English, Bahasa Melayu and 简体中文. Switch at the top of this page, even before you sign up. Syllabus content stays in the language your exam board printed it in, because that is the wording your exam uses.
