Cambridge International A level Chemistry grade calculator

In June 2026, an A needed 185 out of 260 and an E needed 79 on A Level linear (components 11, 21, 31, 41, 51). On A Level linear (components 11, 21, 32, 41, 51), an A needed 183 out of 260 and an E needed 79. On A Level linear (components 12, 22, 33, 42, 52), an A needed 168 out of 260 and an E needed 62. Boundaries are set again for every series, so these are last time's marks rather than the next exam's.

Not always. Schools often mark mocks against an older year's boundaries, sometimes more strictly to leave room to improve, and the real exam's boundaries are set only after it has been marked. A grade from a mock is a useful guide to where things stand, not a prediction of the result.

As a rough guide, yes: Cambridge publishes a boundary for each paper, and the calculator uses those. The real grade comes from the marks for all the papers added together, so one strong or weak paper can be balanced by the others.

Boundaries are set after each exam is marked, so that a grade means the same standard even when one year's paper is harder than another's. A harder paper usually has lower boundaries, so the same mark can be worth a higher grade.
