Assistant Examiner: AI marking for O Level, IGCSE and A Level papers
Our best value: matched the Chief Examiner on every part. Rs 1.50 · $0.0081 · AED 0.03 a page + Rs 25 · $0.14 · AED 0.50 a script.
On the sample script it gave exactly the Chief Examiner’s mark on every part, at about a twelfth of the price on a full paper. Strict on notation and on “show that”.
Best for
- Class tests and mocks
- A good default for most centres
- Checking a whole batch to the board’s standard
Reasons are shorter than the senior examiners’. Tested on one script so far; we are confirming on more subjects.
How it marked a real Pearson Edexcel IAL Pure Mathematics 1 (WMA11), October 2022 script
Whole paper: 45/75.
- 7(a) Range of x for which f(x) < 6, from the graph: 0/3. The mark scheme requires inequalities in terms of x (x < −4, −1 < x < 2, x > 3); a description in words does not score.
- 7(b) Largest solution of f(2x) = 6: 1/1. Correct value of 1.5.
- 8(b) Area of triangle AOB: 2/2. Valid method for the exact area of triangle AOB.
- 8(c) Show that AB = 3√3 m: 1/2. M1 for the cosine rule attempt; the intermediate value (c² = 27 or c = √27) was omitted in a “show that”.
- 8(d) Total area of the pond surface: 0/5. Triangle ABC was completely omitted; the sector was simply added to triangle AOB.
