Real Prelim Papers from Singapore's Top Schools

Genuine past-year Primary 6 preliminary examination papers from Singapore's top and popular schools — Maths (2023–2025), Science (2022–2025) and English (2021–2025), 128 papers in all. They are the real standard your child will face in the PSLE, practised online.

Yes — the school's own answer key is what we work from, and every answer is checked against that key as the paper is built.

Some papers then get a second, deeper pass: we re-solve every question ourselves, independently, and compare. That is where errors surface. Now and then a school's key is simply wrong — a misprint, or an answer that does not hold up once the question is worked through properly. Re-solving the 2023 Maths papers turned up five: one key marked five coins as the way to make $2, when five coins cannot reach $2 at all; another gave 5094 as the number closest to 5000 when 5049 is closer; a third printed $719.69 where its own working says $719.60.

We do not pass those on. We correct them, and we say so here rather than quietly hoping nobody notices — because a child practising against a wrong answer learns the wrong thing and carries it into the exam.

To be straight with you about how far this has gone: the independent re-solve is complete for the 2023 Maths papers and we are working through the rest of the catalogue the same way. Every paper has been checked against its school's key; not every paper has yet had that second independent pass.

Other keys are right but bare — a bare number with no working, or a one-line model answer that would not earn full marks if a real marker saw it. Those we build out into something your child can actually learn from.

So: the answers are the schools', checked and where necessary put right by us. The explanations are ours throughout — schools publish answers, not teaching, so we write the worked reasoning that turns a wrong answer into a lesson.

Practice is untimed. Your child works at their own pace, checks a section whenever they like, and sees the answer and explanation straight away. Progress is shown as a percentage.

Mock Exam is the real thing: the paper is timed, nothing is marked while they work, and they may change any answer until they submit. Only then is the whole paper marked and every explanation revealed. That is the sitting that produces a mark.

The paper submits itself and is marked as it stands. The result is recorded as having exceeded the time limit, so you can see at a glance whether a low mark was about the questions or about pace — which is usually the more useful thing to know before the PSLE.

Three attempts per paper. Every attempt is kept — the mark, the time taken, and whether the clock beat them — so you can watch a paper improve across the three sittings. Practice mode is unlimited, so there is always more to work through.

Multiple-choice and fill-in answers are marked the moment the paper is submitted, each with a worked explanation. Questions that cannot be marked by a machine — written answers, drawings, diagrams — show the model answer broken into its marking points, and your child ticks the ones their answer included to award their own marks. That is how a real marker does it, and it teaches them what earns a mark.

How complete is that? In English and 华文, every question has its own explanation — 5,587 of them, and we check that no two questions share the same wording, so none of it is filler. Maths and Science carry worked solutions and mark schemes throughout; we are still counting those question by question and will say so here when we can put a number on it.

No. Payment is handled by Stripe, and your card is not stored by us and not saved for any future charge. Nothing renews automatically — if you do not renew next year, you simply are not charged.

Every paper is transcribed, checked against the school's own answer key, given a written explanation for each question, and wired into the marking and timing system — then maintained. A single yearly payment is what supports that work and keeps the price where it is. It also means one clean payment instead of twelve small ones you have to remember to cancel.

Yes. Maths, Science, English and 华文 Chinese and Oral are S$60 each. English + Maths + Science + Oral together is S$150, and all five modules is S$199. You only get access to what you buy, and you can add another subject at any time.

Every paper is the school's own written prelim paper, section by section. Here is precisely what is inside each subject:

📖 English — Paper 2 (53 papers, 2021–2025)
Booklet A, multiple-choice: Grammar · Vocabulary (including closest-in-meaning and vocabulary cloze) · Visual Text Comprehension.
Booklet B, written: Grammar Cloze · Editing for Spelling and Grammar · Comprehension Cloze · Synthesis / Transformation · Comprehension (open-ended).

📐 Maths — Paper 1 and Paper 2 (33 papers, 2023–2025)
Paper 1: Booklet A multiple-choice and Booklet B short-answer questions.
Paper 2: the structured and longer problem-solving questions, each with a full worked solution.
Both papers also come as separate timed mock sittings.

🔬 Science — Booklet A and Booklet B (42 papers, 2022–2025)
Booklet A: the multiple-choice section, marked instantly.
Booklet B: the open-ended section, with the mark scheme broken into marking points to self-mark against — diagrams, graphs and data tables all kept intact.

🖌️ 华文 Chinese — 试卷二 (39 papers, 2023–2025)
语文应用 (language use) · 短文填空 (cloze passage) · 完成对话 (complete the dialogue) · 阅读理解一 and 阅读理解二 (both comprehension passages). Every 画线词语 is preserved as the school printed it, and each answer is explained in plain English.

Oral is now its own module. P6 Oral (口试) is sold separately at S$60 and is included in both bundles — ten reading-aloud passages and ten photograph stimuli, each with the examiner's four questions and a model answer at every band.

What is still not included, to be straight with you: Listening Comprehension (听力) and Composition or Situational Writing (English Paper 1 / 华文 试卷一). Those need an audio recording or a human marker, so they are not part of these papers. Everything sold here is the written, markable portion of the prelim — which is where the marks are usually won or lost.

Most schools sat their prelims in the past few weeks, and we are collecting the 2026 papers now. Each one is then transcribed, checked against the school's own answer key and given a written explanation on every question — so we expect them to go live in early September.

If you are already enrolled when they land, they are a free upgrade — they simply appear in whichever subjects you already own, at no extra charge, and you are not asked for anything. After that, the price rises to S$99 a subject for families who have not yet joined. Signing up now is what keeps you on today's price.

Access to that subject stops on its anniversary. Your child's results are not deleted — if you renew, everything is exactly where they left it.

Yes. These are genuine school prelim papers set to the Ministry of Education syllabus and the PSLE examination format.

Any modern browser — laptop, desktop, tablet or phone — with nothing to install.

They are at their best on a laptop or desktop. On a full screen the passage, diagram or data table sits beside the answer area, so your child can see the whole question at once — which is also how it feels sitting the real paper at a desk. A tablet is a comfortable second. A phone is fine for a quick section or for going back over the answers, but a full paper on a small screen is harder work than it needs to be.

Progress follows the account rather than the device, so they can start on a tablet and finish on a laptop without losing anything.
