Mathematics — Upper secondary
In upper secondary the subject changes nature: you are no longer asked to apply but to prove. Many pupils who were solid before disengage at this transition, without anyone identifying it as a change of contract rather than a lack of effort.

They get the answer and lose the marks for reasoning
The pupil can do it but hands in a paper where the reasoning is absent: intermediate steps are in their head, not on the page. In upper secondary the answer alone is worth a fraction of the marks. This is not a comprehension problem, it is an unstated contract.
What the tutor does with your child
The tutor requires the justification to be written before accepting the answer, and works on marked past papers to make the real mark scheme visible. Revising without knowing the mark scheme is training without knowing what you are judged on.
- It changes angle the moment an explanation misses
- It leaves the answer to the pupil and stays alongside until they find it
- It has the result checked by a second route
- It goes back to the missing prerequisite, even one from an earlier year
- It keeps the concept open until the pupil restates it in their own words
Parents' questions
Do we need to redo everything from year 10?
Almost never. The diagnosis identifies the genuinely fragile topics, usually three or four, and revision starts there. Redoing the whole syllabus is the most common way to waste the time left before the exam.
