Not OCR? Same subject, other boards.

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

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 H432. No paper to hand? Ask your teacher which board and course code you are entered for.
