What is a grade threshold?

📏

Minimum raw mark per grade

A grade threshold is the minimum raw mark, published by the board after marking, needed to reach each grade. If the A threshold is 165/200, scoring 165 or above secures an A.

🌊

It changes every series

Thresholds are not fixed percentages. Boards adjust them for paper difficulty and cohort performance — harder papers get lower lines. Last year's 80% for an A says little about this year.

🎯

Your yardstick for grading & retakes

After checking answers, thresholds let you estimate your grade and see how many marks you are from the next one; compare past series before deciding on a retake.

🔥 Highest A* as a share of full marks

English as a Second Language (Feb/Mar) 94% · Mathematics (Feb/Mar) 91% · Mathematics (May/Jun) 89%

📈 Biggest A* rises vs 2025

Geography (Feb/Mar) ↑16 · Biology (Feb/Mar) ↑14 · Computer Science (May/Jun) ↑12

📉 Biggest A* drops vs 2025

Computer Science (Feb/Mar) ↓13 · Mathematics (Feb/Mar) ↓12 · Further Mathematics (May/Jun) ↓12

Higher share = harder A* (more raw marks needed); ↑ up / ↓ down / = flat; 'no A*' is common for Core or AS-only syllabuses.

How to read thresholds

Combined marks decide the final grade

A-Level grades come from weighted totals across AS and A2 papers (commonly 50% + 50%). Combination lines in the table are minimums for that total; single-paper lines are per-paper references only.

Thresholds ≠ percentages

A raw 90/100 is not '90%'. conversions differ by subject and paper totals; compare 'threshold as a share of full marks' across subjects, not raw scores.

Compare series by trend

A single series moves with its paper difficulty. Put 3-5 series together to tell a consistently high threshold from one-off fluctuation.

IGCSE / O-Level grading

Most IGCSE and O-Level subjects grade on 9-1 or A*-G, often with separate Core / Extended lines. Confirm your tier and paper combination first.

FAQ

▸When are thresholds published?

Usually on or just before results day: Feb/Mar series around May, May/Jun around August, Oct/Nov around the following January. This site syncs them immediately.

▸Why do lines differ so much between series?

Each series is set independently from paper difficulty and cohort. May/Jun has the largest cohort; smaller series like Feb/Mar can fluctuate more.

▸Does meeting the threshold guarantee the grade?

The threshold is the exact minimum raw mark; a combined total on the line gets that grade. Rare marking adjustments follow the official statement of results.

▸Are these files official?

Yes. All PDFs come from official board publications (e.g. Cambridge International Grade Threshold Tables), collected as-is per subject and series.

Download thresholds from subject pages

Every subject page organises threshold PDFs by series, alongside papers and mark schemes.
