![🎓 Cambridge Grade Thresholds 2026 – Your Complete Guide to Results Day Results Day is finally here! Whether you're celebrating a well-deserved A* or planning your next steps, Cambridge Classroom has everything you need to understand your grades and prepare for the journey ahead. What Are Grade Thresholds? Grade thresholds (also known as grade boundaries) are the minimum marks required to achieve each grade in a Cambridge examination. After every exam session, Cambridge International publishes official grade threshold tables showing exactly how many raw marks you needed for an A*, A, B, C, and so on. Here's the key thing to understand: grade boundaries change every year. They depend on the difficulty of the papers and how the entire cohort of students performed. A mark that gave you an A* in one session might give you an A in another – and that's completely normal. For example: In the June 2025 session, the A* threshold for O Level Chemistry 5070 was 169 out of 200 marks. That means if you scored 169 or above, you achieved the top grade. Anything below that fell into the A, B, or lower categories. 📥 Download Grade Thresholds for Every Subject – FREE! Cambridge Classroom is proud to offer free PDF downloads of grade threshold tables for all Cambridge IGCSE and O Level subjects. Whether you took: Chemistry (5070 / 0620) Physics (0625) Biology (0610) Mathematics (0580) English (0500) Accounting (0452) Art & Design (0400) or any other Cambridge subject – we have your grade threshold PDF ready for download. 👉 [Download your subject's grade threshold PDF here – completely FREE!] 🎉 To Those Who Achieved Their Goals – CONGRATULATIONS!
