One of the first things worth knowing on results day is exactly how many marks you were from the grade above - and how far clear you were of the grade below. Enter your mark below and this tool works it out from the official 2026 A-Level grade boundaries. It isn’t a prediction: these are the real boundaries.
Every subject has an overall grade boundary - the minimum total mark needed for each grade. This tool takes your total subject mark and compares it with this year’s official boundaries for your board and subject, then tells you the gap to the next grade up and how far you cleared the boundary you reached. The boundaries are the same official figures published by the exam boards on results day.
These are overall subject-level boundaries - the total across all papers. Many students first see separate paper or component marks, or UMS points, which do not add up to these boundaries directly. If in doubt, your school can tell you your total subject mark. We explain the difference in how marks become a grade.
Being a mark or two short is a reason to look into it - not a reason to rush. A review of marking is a check that the mark scheme was applied correctly, and a grade can go up, down or stay the same. A sensible order is:
Enter your overall subject mark above. The tool subtracts it from the next grade’s official 2026 boundary to show the exact gap, and shows how far you are above the boundary you did reach.
Not on its own. Being close is a reason to look into it, but a review can move a grade down as well as up. Establish the distance first, get your script, and speak to your school.
These are whole-subject boundaries. Separate paper/component marks or UMS points won’t line up with them directly - ask your school for your total subject mark.
Normally no. Once boundaries are set for a series they are fixed; they can only change through the formal appeals process in exceptional circumstances. Why boundaries change year to year.
GCSE 2026 results are released on 20 August 2026; we will add GCSE to this tool once the boundaries are published. For now it covers A-Level 2026.
