Junior Examiner: AI marking for O Level, IGCSE and A Level papers
Fast and inexpensive, close to the senior examiners. Rs 0.40 · $0.0022 · AED 0.008 a page + Rs 3 · $0.02 · AED 0.06 a script.
Within two marks of the Chief Examiner across the whole paper. Clear, short reasons. Gives the benefit of the doubt on a “show that” that skips its step.
Best for
- Weekly class tests
- Topic tests across a whole batch
- Practice papers before a mock
Slightly generous on “show that” proofs. Fine for practice; choose Assistant or above when the mark itself matters.
How it marked a real Pearson Edexcel IAL Pure Mathematics 1 (WMA11), October 2022 script
Whole paper: 47/75.
- 7(a) Range of x for which f(x) < 6, from the graph: 1/3. The correct regions are identified (M1), but they are written in words and not as inequalities in x, so A1 and B1 are withheld.
- 7(b) Largest solution of f(2x) = 6: 1/1. Correct: 2x = 3 gives the largest solution x = 1.5.
- 8(b) Area of triangle AOB: 2/2. The value 9√3/4 is correct for triangle AOB, so the method mark and the exact answer are both credited.
- 8(c) Show that AB = 3√3 m: 2/2. Correct cosine rule with the correct angle, simplified to AB = 3√3.
- 8(d) Total area of the pond surface: 0/5. Triangle ABC is omitted completely; no sine rule or triangle area attempt is shown.
