Frequently Asked Questions

What is the CCO cut-off?

The lowest score, as a percentage, that earned each award in a class in a given year. Cut-offs are set class by class after each exam, so they change from year to year; this page has them from 2019-20 to 2025-26.

Does CCO have a Level 2?

No. The CREST Cyber Olympiad is a single-level exam, so medals, Merit Certificates and Honourable Mentions are decided on the Level 1 score.

How are CCO ranks decided when marks are tied?

If two students have the same marks, the student who finished the test in less time ranks higher, then the younger student by date of birth. Students who are still tied share the rank. Ranks are normalised across exam sessions, since each session has its own paper.

Do Class 1 students get ranks in CCO?

No. There are no ranks for the youngest classes, to keep the exam free of pressure; a parent or teacher may assist the child. Students who score 60% or more in the Level 1 exam get a Star Medal and a certificate.
