How predicted grades work for IGCSE

Predicted grades can feel mysterious — a number a teacher writes down that somehow shapes your school report and your applications, before you've even sat the real exam. But there's a clear logic behind them. This guide explains what a predicted grade is, who relies on it, how teachers arrive at one, and how you can make a fair estimate of your own using past papers and real boundaries.

What a predicted grade is

A predicted grade is a teacher's professional judgement of the grade you're most likely to achieve in your final exam, based on the evidence they have so far. It's a forecast, not a promise, and not your final result — the exam board only awards the grade you actually earn on the day. Think of it as a well-informed best estimate at a point in time.

Who uses predicted grades, and why

Predicted grades do real work before results day. They typically appear in:

• School reports, so you and your parents can see whether you're on track.
• Sixth-form and college applications, where entry often depends on expected IGCSE grades.
• University and early application references, especially where offers are made before final results are known.

Because other people make decisions on them, predicted grades are meant to be honest and evidence-based — optimistic enough to open doors, realistic enough to be credible.

How teachers actually form them

A good predicted grade isn't a guess or a hope. Teachers usually weigh up several strands of evidence together:

• Mock exam results, marked against real mark schemes and boundaries — often the single biggest input.
• Coursework and controlled assessment, where the subject includes them.
• Class tests and topic assessments across the year.
• Trajectory — whether you're improving, plateauing or slipping, since a student on a clear upward curve may be predicted above their current average.
• Professional knowledge of the subject and how similar students have performed in past exams.

The key word is pattern. One brilliant mock or one bad test doesn't decide it; teachers look for consistent evidence of what you can do under exam conditions.

Predicted grade vs target grade

These two get muddled constantly, but they answer different questions:

• A predicted grade asks: "Based on the evidence, what will this student most likely get?" It's a forecast.
• A target grade asks: "What should this student be aiming for?" It's a goal, often set to stretch you slightly above where you currently are.

So your target might be a 7 while your prediction is a 6 — that gap isn't a contradiction, it's the point. The target shows the ambition; the prediction shows the current reality. Closing the distance between them is what revision is for.

How to estimate your own predicted grade

You don't have to wait for a teacher to know roughly where you stand. You can build a fair self-estimate:

1. Sit a past paper under real timing. No notes, no pausing the clock — mimic the exam.
2. Mark it against the official mark scheme. Be strict; give yourself only the marks a real examiner would.
3. Combine your papers with the correct weighting to get a subject total.
4. Compare that total to real grade boundaries from several recent sessions, not just one.
5. Repeat across a few papers and look at the pattern — that spread is a far better predictor than a single result.

If you land the same grade across most papers, that's a solid personal prediction. If your results swing wildly, the honest read is "it depends on the day" — and the lower grades in that range show you exactly which topics to shore up.

The limits and caveats

Predicted grades are useful, but hold them loosely:

• They're a snapshot — a prediction made in autumn can be out of date by spring if you work hard (or ease off).
• Mocks are often deliberately marked strictly, so a mock grade can read lower than your eventual result.
• Because real boundaries move each session, any estimate is approximate — treat percentages and boundaries as a guide, not a guarantee.
• A prediction is not a ceiling. Students routinely finish above their predictions by closing gaps in the months that follow.

Turn your marks into a quick estimate

Rather than juggling boundaries by hand, put your past-paper scores into our IGCSE grade calculator. It applies real boundaries, gives you a projected grade for each attempt, and shows how many marks stand between you and the next grade — a fast, honest way to sanity-check your own prediction and plan where to focus next.
