You chose the school with care. The reports are warm, the teachers are plainly good, and your child is doing well. Well, but not quite at the top: a steady run of 7s at IGCSE, or As on letter-graded papers, where you hoped for the grades above; an IB 6 that will not become a 7; an A at A Level that keeps stopping just short of the A*. So you find yourself asking a question that feels almost ungrateful: why is my child struggling at a good school? The honest answer is that they are probably not struggling at all. They have reached the point where a strong school's great strength, teaching a course to a whole class, is no longer enough on its own.
It is a conversation we have often with families in Dubai Hills, Emirates Hills and Arabian Ranches. The family chose well, so why is the last grade so stubborn? The answer is not a failing of the school, the teacher or the child. It is structural, and once you see the structure, the plateau becomes a problem with a shape.
Why a capable child can struggle at a good school
Consider what a strong school is designed to do. It takes a full class through a demanding two-year course, covers the syllabus, sets and marks assessments and prepares everyone for the exam series. The best schools do this superbly.
What no timetable can easily provide is someone whose job is to own one student's individual pattern of lost marks. A teacher marking a set of papers can see that your child scored well. They rarely have the hours to sit with that paper and ask exactly which four marks went missing, why, and whether the same four go missing every time. That is not a lack of care. A lesson is built for the room, and the room has many students in it.
Why the last grade is the hardest: 7 to 9, 6 to 7, A to A*
Reaching a 7 at IGCSE, a 6 in an IB subject or an A at A Level is largely a question of understanding. The student knows the content and can apply it. Moving beyond that is a different kind of work. The top band rewards precision rather than knowledge: reading the command word correctly, structuring an answer the way the mark scheme expects, managing time across a full paper, keeping composure on the unfamiliar question written to stretch the strongest candidates.
At this level the marks being lost are small, scattered and easy to miss. A sign error. A correct explanation that omits the point the examiner wants. A fine essay that does not quite meet the top markband. None of these show up as a weakness on a report. Each one costs only a mark or two. Together they are the difference between a good grade and the top one, and because they are specific to the student, no whole-class lesson is designed to find them.
The scale does not change the logic. Cambridge IGCSEs sat outside England are graded A* to G, while Pearson Edexcel International GCSEs use 9 to 1, so the plateau may read as an A in one family and a 7 in another.

Three things nobody quite owns
Look closely at a student on a plateau and the missing marks usually fall into three areas, each sitting between the school's remit and the student's own.
The first is the student's individual gaps. Not the topics the class found hard, but the particular two or three places where this student's understanding is thinner than it looks. They are often small, sometimes a year or two old, and surface only under exam pressure.
The second is exam technique. Schools teach it, and teach it well, but technique is personal. One student rushes the opening questions and runs out of time. Another writes too much for a four-mark answer and too little for a nine. Another loses nerve on the unseen problem and leaves it blank. The fix for each is different, and it has to be practised on that student's own papers.
The third is mark-scheme fluency, and it is the one most often underestimated. Examiners credit specific points. A student can write a thoughtful answer in their own words and still miss the credit because the key idea is implied rather than stated. Writing for the mark scheme is not a trick. It is knowing what a complete answer looks like before you begin.
The school teaches the course. Someone still has to own the student.
What outside support should offer a strong student
This changes what outside help is for. A student at a strong school does not need the syllabus taught again; their teachers are already doing that. What they need is someone to read recent papers alongside the mark scheme, line by line, until the pattern of lost marks is visible, and then to rehearse technique on those exact weak points rather than on generic practice. The general case for diagnosis over the format of support applies here with particular force: well-aimed work on a strong student's actual lost marks usually does more than broad extra tuition.
So if you are weighing up a tutor for top school students in Dubai, the useful test is not how well they know the subject. It is whether, after one look at your child's papers, they can show you where the marks are going, and whether they will work with the school's teaching rather than around it. Our guide to academic support in Dubai sets out what else to ask.
When a child is struggling at a good school: the student's side
Many students at strong schools have always found the work comfortable. They were quick, and understanding was enough. The plateau is often the first moment their usual way of working stops converting into results, and that can feel unsettling in a way they struggle to put into words.
They need to learn a new habit: studying for marks, not only for understanding. That means revisiting a paper they did reasonably well on, and treating a mock as data rather than a verdict. Handled well, it is a lesson they will need again at university. Handled with pressure and comparison, it can make a capable student anxious. The tone at home matters as much as the plan.
Where to start with the last few marks
The practical starting point is the evidence you already have. Recent tests, marked homework and, above all, mock results hold the pattern. Our note on reading mock results properly explains how to turn them into a plan rather than a worry. From there, the work is narrow and specific: close the individual gaps, sharpen the technique, build fluency with the mark scheme, and repeat until the missing marks stop going missing.
This is the part of a student's education that CuratedPrep is built to own. Our mentorship method begins with diagnosis, sits alongside the school rather than competing with it, and keeps grades, tests and university plans on one route. The first step is a quiet one: the last two sets of marked papers, read together, with the lost marks sorted into gaps, technique and mark scheme.
Common questions
Why is my child struggling at a good school when the teaching is strong?
Usually they are not struggling, they are plateauing. Strong teaching carries capable students into the upper grades, but the final step depends on individual gaps, personal exam technique and mark-scheme fluency. Those are specific to each student, and a whole-class lesson is not designed to find them.
How long does it take to move from a 7 to a 9 at IGCSE, or a 6 to a 7 in IB?
It depends on where the marks are being lost, which is why diagnosis comes first. Technique and mark-scheme habits can improve quickly once they are identified; deeper gaps take longer. Starting soon after a set of mocks gives the most room to practise before the real exams.
Will outside support confuse my child or clash with the school?
It should not, if it is done properly. Good support does not re-teach the course or introduce a competing method. It works from the school's own papers and assessments, focuses on the student's individual pattern of lost marks, and reinforces what their teachers are already asking of them.
