Frequently Asked Questions
There is no fixed percentage for a grade 7 — GCSE grade boundaries are set by each exam board after each exam series based on how all students performed. Historically, grade 7 (equivalent to the old A grade) has typically fallen around 65–73% for most subjects, but it can vary by several percentage points each year. AQA, Edexcel, and OCR publish the official boundaries on GCSE results day in August.
Both are technically passes, but they mean different things. A grade 4 is a "standard pass" (equivalent to the old grade C) and satisfies most basic requirements. A grade 5 is a "strong pass" and is required by most sixth forms for entry to A-Level subjects. For EBacc qualification, you need grade 5 or above in English, maths, sciences, history/geography, and a language.
GCSE grade calculators give estimates based on historical grade boundaries from previous years. They are useful for predicting a likely grade range, but the actual boundaries are not published until results day. A calculator showing 70% might predict grade 7, but the real boundary could be 68% or 74% depending on that year's paper difficulty.
Foundation tier covers grades 1–5 and Higher tier covers grades 4–9. If you sit Foundation tier, the maximum grade you can achieve is a 5. Higher tier allows you to reach grades 7, 8, and 9 but has harder questions. Students aiming for sixth form or A-Levels should generally sit Higher tier in key subjects.
Most GCSE subjects have two or three exam papers, each worth a set percentage of the total marks. Your raw marks from each paper are combined (usually equally weighted at 50% each, or split 60/40 in some subjects). The combined total is then compared against the grade boundary for that overall mark to determine your grade.
Grade 9 sits above the old A* — it was designed to stretch the top performers. In practice, roughly 3–5% of students in any given subject achieve a grade 9. Grades 8 and above correspond roughly to the old A*. Grade 7 maps to the old A grade. Grade 4 aligns with the old C grade.
