Do Mock Exam Results Matter?

The four decisions a mock actually feeds

A mock result does not go anywhere outside the school. What it does is inform decisions the school makes on your behalf, and those decisions are consequential in a way the mark itself is not.

The first of these is the one to watch. For GCSE maths, the Foundation-or-Higher entry is normally settled on mock evidence, and it determines the highest grade available to the student for the rest of the year.

• Tier entry — Foundation caps a student at grade 5, and mock scripts are the main evidence behind the decision.
• Predicted grades — sixth forms and colleges receive a prediction, and mocks are the substance behind it.
• Access arrangements — JCQ requires evidence of a candidate's normal way of working, and timed mock papers are the ordinary form that evidence takes.
• Teaching decisions — set changes, intervention groups, and which topics get retaught before the real thing.

The one thing a mock cannot tell you

It cannot tell you your grade. Three things get in the way, and all three are structural rather than fixable.

The boundaries are borrowed. A school marking a mock applies grade boundaries from a previous series to a paper that is not the paper those boundaries were set for. The content may be incomplete: a January mock in Year 11 usually covers a syllabus that has not finished being taught. And the comparison group is one school's cohort, not the national entry that real boundaries are set against.

A mock score of 42% marked against last June's table tells you where you are in the course. It does not tell you what August will say, and treating it as a verdict is how a recoverable position becomes a demoralised one.

The special consideration misunderstanding

Families often hear that mocks are a safety net if something goes wrong on exam day. It is worth being precise about this, because the belief is half right and the wrong half causes trouble.

Special consideration applies when illness or another serious circumstance affects a candidate at or around the time of the real exam. It works on the paper that was sat, or on the components that were completed. It does not convert a mock result into a grade, and no school can promise that it will.

Where mock evidence genuinely carries weight with an awarding body is access arrangements: a school applying for extra time or a reader has to demonstrate the candidate's normal way of working, and properly run timed papers are how that is shown. That is a real reason to sit mocks under exam conditions rather than a motivational one.

The week after the mock is the part that matters

The mark is the least useful thing on a returned script. Go through it question by question and sort the lost marks into two piles: did not know how, and knew how but lost it. They need completely different responses, and lumping them together is why revision after mocks so often changes nothing.

The first pile is a topic list. The second is almost always about method and time: working not written down, a question started and abandoned, the last page unattempted because the first three took too long.

Then redo the lost-mark questions cold, under time, without the mark scheme in front of you. Reading the mark scheme and agreeing with it feels like learning and is not; producing the answer yourself a week later is the thing that transfers.
