Mock results are back. What now?
A sheet of paper comes out of a bag in mid-December, usually reluctantly, and the number on it is lower than anyone hoped. What happens in the next twenty minutes matters more than the number does. I've watched families handle this well and badly, and the difference isn't the grade.

Why mock grades come back low
Because they're designed to. That's not a comforting platitude, it's how the exercise works.
Schools generally set mock boundaries higher than the real ones, deliberately. A department that hands out generous grades in December gets a cohort that relaxes in January, and every experienced head of maths knows it. So the same paper that would earn a 5 in the summer earns a 4 in the mock, and the student concludes they're a grade worse than they are.
Add the conditions. It's the first time most students have sat a full paper under exam rules, in a hall, with the clock visible. That alone costs marks that have nothing to do with knowing the maths.
The content nobody had taught yet
This is the one that gets left out of the conversation, and it's the biggest single factor.
Mocks are usually sat before the syllabus is finished. Depending on the school, anywhere from a handful of topics to a decent chunk of the course may still be untaught in December. Those questions are on the paper anyway, because it's a real past paper, and your child could not have answered them.
So before drawing any conclusion, find out what hadn't been covered. The maths teacher will tell you, and it takes one email. If a fifth of the paper was on material the class meets in February, the grade is measuring something other than what it appears to measure.
Worth doing before you say anything else: go through the paper and put a small mark next to every question on a topic that hadn't been taught. Then work out the grade from what's left. It's often a full grade higher, and it's a far more honest number to have the conversation about.
Read the breakdown, not the grade
The grade is a single number that compresses a hundred marks into one digit, and almost everything useful is lost in the compression.
What you want is the question-by-question breakdown, which most schools provide and most families never look at. It answers the only question that matters: where did the marks actually go?
Two students can both get a 4 and need completely opposite things. One lost two or three marks on nearly every question, which usually means shaky accuracy, arithmetic slips, or running out of time. The other answered most questions perfectly and scored nothing on three topics, which means specific gaps. The first needs technique work. The second needs teaching. Handing either of them the other's plan wastes a term.
Look for the pattern rather than the total. It's usually visible in ten minutes, and it's the difference between revision that works and revision that just happens.
The conversation to have tonight
Your child already knows the grade was bad. They've been carrying it around since the paper came back, possibly for days, and they've likely rehearsed the moment they show you.
So the information they need from you isn't that it was disappointing.
What helps is treating the paper as data. Sit down with it, not opposite them but next to them, and go through where the marks went. Ask what happened on a particular question rather than why they didn't revise. "What went wrong here?" is a question with an answer. "Why didn't you work harder?" isn't, and it turns the evening into an argument that ends the useful part of the conversation.
Then say the true thing, which is that a December mock is not a verdict. Not as reassurance, but because it's accurate.
One more piece of realism. If your child worked hard and the grade still came back low, that's genuinely worth knowing, and it means the method was wrong rather than the effort. That's a much better problem to have, and my guide on using past papers properly is where I'd start.
What mocks are actually used for
Mocks carry no marks into the summer. The final grade comes entirely from the real exams, and a bad mock cannot pull it down arithmetically.
They do get used for things, though, and it's worth knowing which. Schools set predicted grades from them, which matter for sixth form and college applications. They inform tier entry, so a mock can be part of why a student is moved between Foundation and Higher. And in years when exams have been disrupted, mock evidence has occasionally mattered a great deal.
Serious, then, but not decisive. Both halves of that sentence are worth passing on.
How much time is genuinely left
From December mocks to summer exams is roughly five months. That's a real amount of time, and I've seen students move two grades inside it more than once.
It's also not infinite, and pretending otherwise doesn't help anyone. Five months of nothing changing produces a summer result that looks a lot like the mock. The mock's actual value is that it arrives early enough for the information to be worth something, which is the entire reason schools bother running it.
So the useful response is narrow. Pick the two or three topics the breakdown flagged. Fix those, properly, rather than starting a general revision programme that covers everything thinly. Then run another past paper in a few weeks and see whether the marks moved, because that's the only real test of whether the fix worked. If the grade needs to move a long way, the accuracy habits that close the gap are worth reading too.
Common questions
Are GCSE mock grades a good predictor of the real thing?
They're a reasonable snapshot of where a student stands partway through, and a poor prediction of the final grade. Mocks are usually sat before the syllabus is finished and marked against deliberately demanding boundaries, so most students finish above their mock. Treat it as a diagnosis rather than a forecast.
Should I be worried about a grade 3 in the mocks?
Take it seriously without treating it as settled. A 3 in December is a long way from a 3 in the summer, especially if topics were untaught or the marking was harsh. What matters is the breakdown: a student a few marks under across many questions needs something quite different from one who lost everything in two topics.
Do GCSE mock exams count towards the final grade?
No. The final grade comes entirely from the summer exams and a mock carries no marks into them. Mocks still matter for predicted grades, for confirming tier entry, and occasionally as evidence if exams are disrupted, so they're worth taking seriously without being decisive.
