Full-length mocks, sat the way the real paper is sat

ExamEdge mock tests run at full length under the real time limit and marking scheme, including negative marking, with percentile against everyone who sat the same paper. After submission you get a per-question and per-topic breakdown of where the marks went.

Percentile is against the ExamEdge cohort for that paper, which is not the national cohort. The two differ, and we label which one you are seeing.

The point of a mock is not the score. It is finding out what happens to you across three hours — which section you rush, where you lose time, and what you get wrong when you are tired rather than when you are fresh.

A twenty-minute practice set cannot tell you any of that, which is why mocks and practice are different things and both are necessary.

01

What the breakdown tells you that the score does not

  • Where time went. Minutes per question, so you can see the four questions that ate twenty minutes and produced nothing.
  • Accuracy against speed, per section. Being slow in physics and inaccurate in chemistry are different problems needing different weeks.
  • What you attempted and got wrong versus skipped. A skipped question you could have done is a different failure from a wrong one you should have skipped.
  • Guessing cost. How many marks your guesses gained or lost across the paper, which almost nobody measures and most people get wrong.

How often to sit one

Less often than most candidates think, until the last few months. A mock is only useful if you have time to act on what it tells you, and a mock every week from June leaves no time for the acting.

Roughly one a fortnight through the building phase, moving to weekly and then twice-weekly in the final stretch, is a defensible shape. Sitting mocks constantly and never reviewing them is a way of feeling productive without improving.

FAQ

Questions people ask

Phrased the way they arrive, answered so each one stands on its own.

How many mock tests should I take?

Fewer early, more later. About one a fortnight while you are still building, weekly in the last few months, twice-weekly in the final weeks. A mock you do not have time to review is worth almost nothing.

Is the percentile a national percentile?

No. It is against everyone who sat that paper on ExamEdge, and we label it as such. A national percentile comes from the examining body after the actual exam and cannot be derived beforehand.

Are the mocks the same difficulty as the real exam?

They are built to the same blueprint and marking scheme. Difficulty is calibrated against past papers, but no mock predicts a specific year, and treating your mock score as a forecast is a mistake.
