What we hold
We hold 163 papers from 48 sittings, Oct/Nov 2002 to May/June 2026.
Full title
Cambridge O Level Science - Combined

Not Cambridge? Same subject, other boards.

Each board sets completely different papers. Check yours before you revise the wrong thing for months.

Cambridge is the only board we hold for Cambridge O Level Combined Science.

The board and course code are printed on the front of every mock paper.

HELP. Which board am I??

Find a mock or past paper from school. The board's name is at the top of the front cover, and the course code is printed next to it, like 5129. No paper to hand? Ask your teacher which board and course code you are entered for.
