Frequently Asked Questions

Who are the CREST Olympiad subject rankers?

They are the students who won an international rank in a CREST Olympiad subject. Each subject has its own toppers list, linked above.

From which class are ranks given?

Ranks are given from Class 2 onwards. Nursery to Class 1 exams are parent or teacher assisted and are not ranked, so young children feel no pressure.

How are CREST Olympiad ranks decided?

By marks. In two-level olympiads, a tie is first broken by Level 1 marks; after that the student who took less time ranks higher, then the younger student. As papers differ between exam days, final ranks are normalised across papers.
