Is Holy Grail free, and what does the Premium pass offer?

Updated

Holy Grail (grail.moe) offers free summary notes and practice papers for O-Level, A-Level, and IB students in Singapore, and it also has a paid Premium option. The free tier is the core of the site: the homepage states plainly that it provides "Free summary notes and practice papers" curated by students. At the same time, the site's navigation includes a Pricing page and a link to "Get Premium for a month," so a paid tier clearly exists. What the public materials do not spell out is exactly what Premium unlocks, how much it costs, or how payment works — those details live behind the pricing page itself.

What you get for free

Based on the site's own description, the free offering is not a teaser but the main library:

  • Summary notes across exam levels
  • Practice papers for the same subjects
  • Coverage for O-Level, A-Level, and IB, aimed at students in Singapore
  • Community contribution — students can sign up to share their own notes

The subject lists shown on the homepage include:

Level Example subjects listed
O-Level Mathematics, Physics, Chemistry, Biology (+2 more)
A-Level H2 Math, H2 Physics, H2 Chemistry, H2 Economics (+1 more)
IB Math AA/AI, Physics, Chemistry, Economics (+1 more)

So if your goal is simply to find notes and practice papers for these levels, the free library is the place to start.

What the Premium pass appears to be

The only concrete signal about Premium is a link labeled "Get Premium for a month" pointing to grail.moe/pricing?buy=pass-1. That tells you two things:

  1. Premium is sold as a time-limited pass (at least a one-month option exists).
  2. It is a separate purchase from the free library.

What the available information does not confirm:

  • The price of the pass
  • Which specific features or content Premium unlocks
  • Accepted payment methods
  • Whether Premium removes limits, adds content, or offers something else entirely

If any of those matter to your decision, check the Pricing page directly rather than assuming.

How to decide

Stick with the free tier if you only need summary notes and practice papers for O-Level, A-Level, or IB subjects — that is exactly what the site advertises as free.

Look into Premium if you want whatever additional access the pass provides. Because the difference between free and Premium is not documented in the public description, the practical step is to open the Pricing page and compare what each tier includes before buying.

Consider contributing if you want to give back — the site invites students to sign up and share notes with others across Singapore.

A quick way to check for yourself

  1. Go to grail.moe and browse the Library by subject to confirm the free notes and papers cover your exam and topic.
  2. Open the Pricing page to see the current cost of the Premium pass and what it includes.
  3. Compare that list against what you actually need — if the free library already covers your subjects, the pass may not add anything you require.

The key takeaway: Holy Grail's notes and practice papers are free, and Premium is an optional monthly pass whose specific benefits and price you should verify on the Pricing page before deciding.
