What Is an Exam Series?

One window, one timetable, one results day

Everything inside a series moves together. The board publishes a timetable so that a given paper is sat at the same time in every centre that offers it. Scripts come back, are marked, and only then are grade boundaries set for that series and no other. Results are released on a single day, and certificates follow later.

The dates attach to the series rather than to the subject. UK GCSE results for the summer series land in late August. Cambridge International June results are issued in August and its October/November results in January, which is why an international student who resits in November waits into the new year to know where they stand.

The series a maths candidate can actually sit

For GCSE Mathematics in England there are two: the main May/June series, and a November series which exists for resit candidates — in practice students past 16 who did not reach grade 4 and must keep going. That is a narrow list, and it is the reason a missed grade means a wait of roughly five months rather than a rebooking.

Cambridge International runs a June series and an October/November series worldwide, plus a February/March series available in some countries and for a subset of syllabuses. Boards also publish timetables for series belonging to their other qualifications, so check that the timetable in front of you is the GCSE one before planning a year around it.

• May/June — the main series for GCSE and A level in the UK; results in August
• November — GCSE English Language and Mathematics resits; results in the new year
• Cambridge October/November — full international series; results in January
• Cambridge February/March — offered in some countries only, for some syllabuses

Entries close long before anyone opens a paper

The entry, not the exam, is the deadline that catches families out. Centres submit entries to the board months ahead of the summer series, late entries carry higher fees up to a final cut-off, and every school sets its own internal deadline earlier still so that it can collate the cohort before the board's date falls.

Two consequences are worth knowing. Changing tier — Foundation to Higher or back — is normally possible after the initial entry but has its own deadline, so a decision made in April may be too late. And a private candidate has to find a centre that accepts external candidates before any of this begins; those places fill and close entries earliest of all.
