| June 2024 | 251 | 84% |
Across the 3 years on record this boundary has ranged from 251 to 258 — a spread of 7 marks. Aiming at the most recent figure means aiming at the middle of a moving target, so 260 is the safer number: the highest it has been, plus a small buffer for a year that has not happened yet.
Boundaries are set after every paper is marked, precisely so that a grade means the same thing in an easy year and a hard one. That is why nobody — not this page, not your teacher, not the board — can tell you next summer's number in advance. Anyone who gives you one exactly is guessing.
254 out of 300 — 85% — on the June 2026 boundaries. Across the years on record it has ranged 251 to 258, so aim nearer 260.
Almost certainly not. Boundaries are set after marking so that a grade represents the same standard however hard the paper was. A harder paper gets a lower boundary and an easier one gets a higher boundary.
44 marks on the most recent boundaries — usually a question or two, not a different student.
