Treat any “predicted paper” as a guess, and treat any pack that claims the real questions as something to avoid. Before you spend time on a pack, run five quick checks on where it came from and what it covers.
Close to the exam, a confident label is tempting. A label proves nothing, and the time lost on a wrong pack is time taken from topics that really are examined.
What is the difference between a prediction and a leak?
A prediction is someone’s guess about topics or question styles. It may be sensible or careless, but it is a guess, and it is not a statement from Cambridge.
A leak is exam content released before the paper by someone who should not have it. Using it is malpractice and is not a shortcut. If you are offered something that looks like the real paper, decline it and mention it to your exam centre, which handles your entry and your candidate rules.
The five checks
- Source: who wrote it, and can you name them? An anonymous file in a chat group fails.
- Code and year: does it state the syllabus code and exam year it was written for?
- The promise: does it claim to know the exact questions or “examiner” information? If yes, stop.
- Coverage: do the topics match the current syllabus list, including topics the pack leaves out?
- Answers: are there worked solutions that explain the reasoning, or only a bare answer list?
Worked example: one pack, five checks
A student receives a file called “Chemistry final predicted paper, sure topics” in a group chat. Here is how it scores.
| Check | What the student finds | Result |
|---|---|---|
| Source | No author, forwarded three times | Fail |
| Code and year | Says “Chemistry”, no code, no year | Fail |
| The promise | “Sure topics from examiner contact” | Fail |
| Coverage | 6 of the 10 syllabus topics appear | Partial |
| Answers | Answer letters only | Fail |
One partial and four fails. The pack goes in the bin. The student keeps the coverage point, because it shows a second risk.
The mistake to watch for
The pack covers 6 of 10 topics, so a student who revises only those leaves 4 untouched, which is 40 per cent of the topics. The pack’s claim “these are the only ones” lulls her into skipping them.
The correction is simple. Use the syllabus, not the pack, as the list of what can appear. Any pack should be a small extra, never a replacement for covering every topic.
Check yourself
1. A teacher gives out a practice paper she wrote, marked “original practice, not an exam paper”, with full worked solutions. Is it a predicted paper?
Show answer
No. It is honest practice with a clear source and explanations. It is a good use of revision time, as long as it covers topics across the whole syllabus.
2. A group chat promises “tomorrow’s exact questions” for a small fee. What do you do?
Show answer
Do not pay, open or forward it. The promise itself is the warning. If the content is real it is a leak, and if not it is a scam. Tell your exam centre if you are worried.
3. You find a past paper from several years ago. What must you check before relying on it?
Show answer
Check its syllabus code and year against the Cambridge subject page for your own exam year. If the syllabus has changed, some questions may test content you do not need, or miss content you do.
Where this leads next
Put safe practice inside a revision window you have counted honestly, and use active practice rather than another summary to decide each session. The original mixed-practice builder gives you reviewed questions with solutions, and it makes no claim to predict the paper.
For the official syllabus, use the Cambridge subject page for your subject and year. If you want a teacher to write and mark original exam-style questions for you, one-to-one Mathematics tuition is one place to start. The students page lists other situations we help with.
