A grade boundary is the lowest total mark that earns a grade. Exam boards set them after the exams, once marking is nearly complete, and they change from year to year with how demanding the papers were (Ofqual). To use them with a past paper, add up your child's marks across all of that year's papers and compare the total with that year's row, which is out of the same maximum. Each year links to its papers.
June 2026, board by board
The marks needed for grade C and A in June 2026, as a share of each board's maximum. Each board writes its own papers and sets boundaries for them, so a lower boundary doesn't mean a board's exam is easier to pass.
