My Child Is Behind for GCSEs. Is It Too Late?

Mock results come back and a significant number of parents discover their child is further behind than they thought. Some are disappointed by a single subject. Others are looking at results across the board that do not reflect two years of effort. In both cases, the first question is the same: is there still time to turn this around?

The short answer is yes. The more useful answer is: it depends on what you do next, and how quickly you start doing it. This post is for parents who have seen the mock results and want to understand honestly what is possible between now and the real exams.

How much can actually change between mocks and real exams

A lot. Students move two or three grade levels between mock results and final exams every year. This is not unusual — it is expected. The mock series is sat before the most focused revision period of the year, often before topics have been fully taught, and under conditions that many students have not prepared for specifically. The final exams are sat after months of targeted revision with full knowledge of the specification.

The students who make the biggest jumps are not always the ones who were closest to the grade they needed. They are the ones who responded to mock results with a clear plan rather than panic or avoidance, and who spent the available time on the right things. A grade 4 student who identifies the specific topics costing marks and addresses them methodically can reach a 6 by May. It is not guaranteed, and it requires real effort — but it is well within the range of what is possible.

What tends to hold students back at this stage

When students are behind at mock stage, the cause is almost always one of three things. The first is content gaps — topics that were not understood when taught and have not been revisited. The second is exam technique — the student understands the material but writes answers that do not match what the mark scheme rewards. The third is revision method — the student is putting in hours but using approaches that do not build the recall needed under exam conditions.

Each of these has a different fix. Content gaps need targeted teaching on the specific topics causing most mark loss. Exam technique needs practice with mark schemes and feedback on answers. Poor revision method needs a change in approach — away from passive re-reading and toward active recall and past paper practice. Identifying which of these is the primary issue for your child is the first step, and the most valuable thing a tutor can do in an initial session.

What to do in the next two weeks

The two weeks immediately following mock results are the most important period of the whole GCSE course. Students who act quickly and purposefully in this window recover ground. Students who feel overwhelmed and don’t know where to start often let another month slip by before doing anything meaningful.

Go through the mock paper with the mark scheme

Sit down with your child and their mock papers within a week of getting results back. Go through each question they lost marks on and look at the mark scheme. For each lost mark, ask: did they not know the answer, or did they know it but write something that didn’t match what the examiner was looking for? The distinction is crucial. Mark scheme misalignment is often faster to fix than a genuine content gap — it is a habit rather than a knowledge problem.

Build a subject priority list

List every subject and note two things against each: the current mock grade and the grade your child needs. The subjects where the gap is two grades or more and the exams are earliest get priority. The subjects where your child is already at their target grade get less time. Most students revise the subjects they enjoy most, because it feels productive and is not uncomfortable. The marks they need are almost always in the subjects they have been avoiding.

Start focused revision immediately, not after half term

The instinct after a difficult mock period is often to take a break before starting revision in earnest. This is understandable and partially sensible — a student who is exhausted and demoralised needs some recovery time. But “I’ll start properly after half term” often becomes “I’ll start properly in April” and then the time has gone. A manageable amount of focused revision starting now is worth far more than an intensive burst that begins too late.

The conversation to have with your child

How you respond to mock results at home matters. A student who hears primarily catastrophising — conversations about what the results mean for their future, comparisons to what other people got, expressions of disappointment that are repeated — is more likely to freeze than to mobilise. That is not because they don’t care. It is because anxiety narrows focus, and a student under significant anxiety finds it much harder to sit down and do the work.

The most useful framing is honest and practical. Acknowledge that the results were not what either of you hoped for. Be clear that there is time to change them. Then focus the conversation entirely on what happens next — which subjects, which topics, how much revision per day, and whether a tutor would help. Action is the antidote to the paralysis that bad mock results can cause, and your child needs help identifying what that action looks like.

When a tutor makes the most difference

A tutor is most valuable at this stage when the student needs both a diagnosis and a plan. The diagnostic part — working out exactly which topics and techniques are costing marks — is something a good tutor can do in a single session by going through a mock paper in detail. The plan part follows from that: a subject-specific, week-by-week revision schedule focused on the marks available to recover in the time remaining.

Students who are behind in multiple subjects benefit from one tutor per priority subject rather than one generalist tutor across everything. A specialist Maths tutor will identify mark-scheme issues in Maths Maths in a session that a generalist might miss. We match by subject and level — if your child needs support across two or three subjects, we can arrange multiple tutors quickly without you having to search separately for each.

Meet some of our GCSE tutors

Ejaz

Ejaz is reading for an MSci in Mathematics at Imperial College London, where he achieved 8 Grade 9s at GCSE. With over 100 hours of tutoring experience across GCSE and A Level Maths, he is particularly effective at identifying whether a student’s errors come from weak foundations or mark-scheme misalignment — and adjusting the approach accordingly. Students who are behind in Maths after mocks consistently make up ground quickly under his guidance.

Clemmie

Clemmie read Psychological and Behavioural Sciences at Trinity College Cambridge (First Class), having achieved A* in Biology, Chemistry, and Maths at A Level. She tutors GCSE Maths, Biology, Chemistry, and Physics. Her research background gives her a precise, analytical approach to diagnosing where a student is losing marks and building a targeted plan around what the mark scheme actually rewards — which is often the fastest route to improvement after a disappointing set of mocks.

Naomi

Naomi read Politics, Philosophy, and Economics at Oxford (Exeter College), winning the Sir Arthur Benson Memorial Prize. She achieved seven Grade 9s at GCSE and tutors GCSE English Language, English Literature, and humanities subjects. One of her students raised a predicted English grade from a 6 to a 9 through consistent, structured practice. Naomi is particularly effective at helping students understand what the mark scheme rewards in English and building the analytical habits that move answers into higher grade bands.

There is still time. Use it well.

The families who look back on GCSE results day and feel proud of what their child achieved are almost never the ones who panicked after mocks.
