Cambridge O Levelexam timetable June 2027 – Zone 3

The Cambridge O Level exams run from Monday, 26 April 2027 to Friday, 11 June 2027, across 27 subjects and 62 papers.

Cambridge gives each school its own Key Times — the morning and afternoon start times for its location — so this timetable shows each paper's session (morning, afternoon or, in some zones, evening) rather than a clock time. Look up your Key Times on Cambridge's website; your school's own timetable confirms the exact time, your room and seat.

Cambridge puts every school in one of six administrative zones by its location, and each zone has its own timetable — the same exam can fall on a different day or in a different session, with a different paper code. Use Cambridge's zone checker or ask your exams officer. Zone 3 includes the UK: Cambridge's UK timetable lists exactly the same papers.

You take them one after the other in that session, and your school may give you a supervised break between them. The planner above flags these sessions, and your exams officer arranges the order.

It's the exam board's published timetable. Your school's version is the one that counts for you: it confirms your room, the exact start time and any access arrangements, such as extra time, which aren't included here.
