Which exams and subjects does Holy Grail cover?

Updated

Holy Grail (grail.moe) covers three exam systems for students in Singapore: O-Level, A-Level, and IB. For each system, the site provides free summary notes and practice papers, organized by subject in its Library. If you are preparing for one of these three qualifications, the platform is likely to have material relevant to you; if you are studying for a different exam system, it is not designed for your case.

Coverage at a glance

Exam system Student level Subjects shown on the site
O-Level Secondary students Mathematics, Physics, Chemistry, Biology, plus 2 more
A-Level JC students H2 Math, H2 Physics, H2 Chemistry, H2 Economics, plus 1 more
IB International Baccalaureate Math AA/AI, Physics, Chemistry, Economics, plus 1 more

The "+ 2 more" and "+ 1 more" labels indicate that the listed subjects are highlights rather than the complete catalogue. To see everything available, browse the full subject list in the Library.

How to check whether your subject is covered

  1. Open the Library on grail.moe.
  2. Choose your exam system — O-Level, A-Level, or IB.
  3. Browse the subject list for the exact subject and level you are taking (for example, H2 Chemistry rather than Chemistry in general).
  4. Open a subject to see the notes and practice papers available for it.

The expected result is a set of summary notes and practice papers you can use for revision. If a subject does not appear under your exam system, it is not currently part of the catalogue.

What the material is

  • Summary notes — condensed revision notes.
  • Practice papers — papers for exam practice.
  • Curated by students, for students — the content is contributed by a student community, and the site invites students to sign up and share their own notes.

Because contributions come from students, treat the notes as a revision aid rather than an official syllabus document, and cross-check anything critical against your school or examination board materials.

Practical notes

  • The site states the notes and practice papers are free.
  • A Pricing page and a "Get Premium for a month" option also exist, so some features or access may sit behind a paid pass. Check the pricing page directly if you need to know what a premium pass includes.
  • Coverage is aimed at Singapore students, so the O-Level, A-Level, and IB content follows that context.

Quick answer

If you are taking O-Level, A-Level, or IB exams in Singapore, Holy Grail covers your exam system and lists subjects including Maths, Physics, Chemistry, Biology, and Economics (with H2 variants at A-Level and Math AA/AI at IB). Browse the Library by exam and subject to confirm your specific subject is there before relying on it for revision.
