What we publish
Today we cover 29 subjects across Singapore Secondary, Cambridge IGCSE and UK GCSE. Every chapter and topic has the same kit, so you always know where things are:
- Notes with key terms, worked examples and common mistakes.
- A quiz that explains every answer and links back to the notes.
- Topical questions in three tiers (foundation, standard, challenging) with model answers.
- Printable practice papers — weighted-assessment, end-of-year and prelim-style papers for Singapore subjects, paper-style sets for IGCSE and GCSE, and a short paper for every chapter and topic — each with a separate mark scheme.
Notes and key points are free to read; a free account adds quizzes, paper downloads and AI practice, and Pro opens every unit in full with a mark scheme for every practice paper. See every subject by curriculum and level
Who runs QuizQuip
QuizQuip is run by SudoAI, an independent developer, the same operator named in our terms of service. Pages are published under the QuizQuip name rather than an individual byline; we do not put invented author names or credentials on any page.
We are not affiliated with, or endorsed by, the Singapore Ministry of Education, SEAB, Cambridge University Press & Assessment, the Department for Education, AQA, Pearson Edexcel, OCR or any school. Notes are free to read and the optional Pro plan pays for the site; any advertising is labelled and kept apart from notes, questions and answers.
How we write and check our notes
Every subject goes through the same steps before its pages are published:
- Syllabus first. Each subject starts from its official syllabus document: the MOE / SEAB syllabus for each Singapore subject, the Cambridge International syllabus for each IGCSE subject, and the DfE subject content shared by the AQA, Edexcel and OCR specifications for GCSE. Chapters follow the syllabus order, and every scored quiz question is tied to a learning outcome from that syllabus.
- AI-assisted drafting. Notes, questions, explanations and practice papers are drafted with AI writing tools, working from the syllabus and from a list of the mistakes students commonly make in each chapter.
- Automated checks on every item. Before anything is published, and again on every later change, automated checks confirm that each quiz question has exactly four options and one correct answer, that every wrong option is tied to a specific misconception, that every explanation says why the answer is right and why the most tempting wrong option is wrong, that no question is reused across the chapters of a subject, that the correct option is almost never given away by being the longest, and that practice-paper marks add up and durations match their total marks.
- Review passes. Separate AI review passes, run apart from the drafting, have re-checked answer keys, explanations and syllabus coverage subject by subject; a disagreement is settled against the syllabus and first principles, not by a vote. Pages are also spot-read, and wrong answers found this way are fixed straight away.
The notes have not yet been reviewed by a teacher or examiner. Treat them as a careful study aid that follows your syllabus, and check with your teacher where your school teaches something differently. When a subject has been reviewed by a teacher, we will say so on its pages.
Original material
Questions, worked examples, diagrams and practice papers are written for QuizQuip. We do not copy or adapt past examination papers, ten-year series, school papers, tuition notes or textbook exercises. Our practice papers are exam-style: they follow the published format of the real papers (sections, question types and mark allocation) but are not past papers and are not set or endorsed by any exam board.
Syllabus codes and learning-outcome wording are quoted only to show which part of the syllabus a page covers.
Corrections
Spotted a wrong answer, an unclear question or something your school teaches differently? Use "Report a problem" at the bottom of any page or on any question, or write to us through the contact page. Tell us the page and the question number. We usually reply within two business days.
Wrong answers and factual errors are fixed first. A fix changes the page itself, and its "Last updated" date moves to the day of the change.
How dates are shown
Every chapter and topic page shows "Last updated" at the end of its notes. It is the date the page’s content (notes, questions or practice paper) last changed, and it is the same date we give search engines in the page’s structured data and in our sitemap. We do not show a first-published date, because our records do not hold one reliably.
What comes next
We add one syllabus at a time and publish a subject only when its chapters are written and checked. Further regions are planned: Malaysia (SPM / KSSM), Hong Kong (HKDSE). There are no dates yet.
