Examiner: AI marking for O Level, IGCSE and A Level papers
Careful written reasons, generous on wording. Rs 3.50 · $0.02 · AED 0.07 a page + Rs 21 · $0.11 · AED 0.42 a script.
Detailed reasons on every part. Strict on “show that”, but accepts a correct answer described in words where the scheme wants notation.
Best for
- Learning-focused feedback
- Practice papers where the student reads every comment
- Topic tests
Can be a mark or two above the board on wording and notation. Not our first choice for a final mock.
How it marked a real Pearson Edexcel IAL Pure Mathematics 1 (WMA11), October 2022 script
Whole paper: 48/75.
- 7(a) Range of x for which f(x) < 6, from the graph: 3/3. The words correctly describe x < −4, −1 < x < 2 and x > 3, earning M1 A1 B1.
- 7(b) Largest solution of f(2x) = 6: 1/1. The largest solution is correct, earning B1.
- 8(b) Area of triangle AOB: 2/2. Using AB and OA with their included angle π/6 is a correct alternative method, earning M1 A1.
- 8(c) Show that AB = 3√3 m: 1/2. M1 for the correct cosine-rule setup; the accuracy mark is withheld because no intermediate such as c² = 27 is shown.
- 8(d) Total area of the pond surface: 0/5. No method to find triangle ABC, so neither its method mark nor the total-area marks are earned.
