Exam Score Calculator

This calculator converts raw exam marks into percentages and maps them to grade boundaries. Enter the marks achieved and the total marks available, and it produces a percentage score. You can then compare this against grade boundaries to determine the grade.

Grade boundaries vary by qualification type. For GCSEs (9–1), typical boundaries might be: Grade 9 at 80%+, Grade 7 at 65%+, Grade 4 (pass) at 40%+. For A-levels: A* at 80%+, A at 70%+, B at 60%+. These are illustrative — actual boundaries depend on the exam board, subject and year.

The calculator also supports pass/fail assessments (common in professional qualifications), where you simply need to exceed a set pass mark. Enter your score and pass mark to see whether you have passed and by what margin.

UK GCSE grade boundaries 2025/26. 9-1 grading. Grade 9: top 5-8%, usually 90%+ scores. Grade 8: ~A*. Grade 7: ~A (90% in sciences/maths typical). Grade 6: high B. Grade 5: 'strong pass' — low B/high C. Grade 4: 'standard pass' — low C. Grades 3-1: D-G equivalent. Boundaries set per exam paper, vary year-on-year. Sample 2025 Maths Higher: Grade 9 = 197/300 (66%); Grade 4 = 75/300 (25%). Foundation tier: max Grade 5.

UK A-level grading 2025/26. A* — 90%+ (since 2010). A — 80%+. B — 70%+. C — 60%+. D — 50%+. E — 40%+. U (Unclassified) — below 40%. Some subjects have lower thresholds (chemistry A* often achievable at 84-86%). Grade boundaries adjusted annually for paper difficulty. UCAS Tariff: A* = 56 points; A = 48; B = 40; C = 32; D = 24; E = 16. AS-level: A = 20 (worth 40% of A-level).

UK university degree classifications. First Class (1st): 70%+ — top ~30% of graduates. Upper Second (2:1): 60-69% — most common, ~45-50%. Lower Second (2:2): 50-59% — ~15-20%. Third (3rd): 40-49% — ~3-5%. Pass: 35-39% — ordinary degree without honours. Fail: below 35%. Some Russell Group degrees: more rigorous boundaries (Oxbridge 1st often 70%+ in finals across all papers, not average). Most employers/postgrad courses require 2:1 minimum.

Weighting and combined exams. Many UK qualifications combine multiple components. GCSE Mathematics (3 papers): equal 33% weighting each. A-level Biology: typically Paper 1 (33%), Paper 2 (33%), Paper 3 (34%) — equal weight. A-level Chemistry: Paper 1 (37%), Paper 2 (37%), Paper 3 (26%). Coursework counts where applicable (English Lit 20% NEA, no coursework most science subjects). Calculate final %: (P1 × weight1) + (P2 × weight2) + (P3 × weight3) ÷ total weights × 100.

Resits and grade improvement. GCSEs: unlimited resits, best grade counts. November exams English/Maths only. New A-level system 2017+: linear assessment — full set of papers retaken if resitting. Resits cost £40-£80 per subject (private), free at sixth form. Universities: best grade reported on transcript, no penalty for resits. Apprenticeships and most employers: no record of resit attempts. UCAS application: report current best predicted/achieved grades. Strategy for retake: identify weak topics specifically, targeted practice; new exam board sometimes easier (e.g. AQA → Edexcel).
