What a Mathematics diagnostic tells you
Exam Diagnostics ZA is a South African service that marks a full Grade 10–12 mock exam paper mark by mark and reports every lost mark, with a strategy report and a video walkthrough, within 24 hours. For Mathematics that means a mark, and beside it the mark your child would have had without the mistakes that had nothing to do with knowing the work.
The mark sits still. Your child studies, redoes exercises, and comes back with the same number. Mathematics is the subject where a pupil can know most of the paper and still lose a third of it.
What Mathematics Paper 1 and Paper 2 cover
Mathematics is examined in two papers. Paper 1 covers algebra, functions, finance and calculus. Paper 2 covers geometry, trigonometry and statistics. You choose which one your child writes when you order, so you can diagnose the paper that is actually costing marks.
The CAPS Grade 12 split. Grades 10 and 11 follow the same shape with less content.
Paper
Focus
Main topics
Paper 1
Algebra, functions, finance and calculus.
Algebra, equations and inequalities; Number patterns and sequences; Functions and graphs; Finance, growth and decay; Differential calculus; Probability
Paper 2
Geometry, trigonometry and statistics.
Statistics and regression; Analytical geometry; Trigonometry, including 2D and 3D problems; Euclidean geometry and the circle theorems; Measurement
Grade 12 paper length: 150 marks in 3 hours.
IEB: The IEB examines the same curriculum but tends to set longer, context-led questions, so reading carefully and choosing an order of attack matter more.
Where Mathematics marks are usually lost
Marks leave a paper for five reasons, and only two of them mean your child did not know the work. In Mathematics the most common are accuracy and not written down — both of which come from how the paper was written, not from what was studied.
Accuracy. A sign dropped in line two carries through to an answer marked wrong, even though everything after the slip was right.
Not written down. The answer appears without the working that earns the method marks, or the last question is left half-finished because the clock ran out.
Wrong method. A question is answered with a method that cannot reach the answer, usually because it looks like a question from another topic.
Every lost mark is sorted into one of five reasons.
Reason
What it means
Recoverable?
Wrong method
The route chosen could not reach the answer.
No — this is a gap to teach
Accuracy
The method was right; the arithmetic slipped.
Yes — the method was right
Not written down
The working stopped before the mark was earned.
Yes — the method was right
Misread
A value or instruction was taken off the paper wrongly.
No — this is a gap to teach
Didn’t remember
A formula or definition was not recalled in the moment.
No — this is a gap to teach
What you get back
Marks come back within 1 hour and the full report within 24, by email and WhatsApp. It runs to eight pages: the mark, the mark in reach, every lost mark with its reason, the recoverable marks question by question, and the concepts behind them.

Choose the grade
The paper is set for the grade your child is in, so a Grade 10 diagnostic is a Grade 10 paper. Pick the grade below to see what that year's Mathematics paper asks for and when in the year a diagnostic is worth writing.
Questions parents ask
Which Mathematics paper should my child write?
The one the marks are going missing in. Paper 1 covers algebra, functions, finance and calculus. Paper 2 covers geometry, trigonometry and statistics. If you are not sure, a school report or a returned test usually shows which paper is the weaker one.
Is the paper CAPS or IEB?
Both are available. You choose the curriculum when you order, once per order, because a family is normally at one school. The IEB examines the same curriculum but tends to set longer, context-led questions, so reading carefully and choosing an order of attack matter more.
What does a Mathematics diagnostic cost?
A single paper is R299. Mark Recovery, both papers of a subject and a follow-up paper, is R749. Finals Ready, three subjects, is R1,990. A printed copy couriered to you is R250 for the order. A follow-up paper on its own is R250; in Mark Recovery it is included.
What if the report finds nothing worth fixing?
Then you do not pay for it. If a paper turns up fewer than 10 recoverable marks, that paper is refunded.
