A-Level Guides

Straightforward explainers for Cambridge International AS & A Level students and parents — written to demystify the numbers behind your results.

A-Level grading can feel like a black box: you sit several papers, wait weeks, and a single letter appears. These guides open that box. They explain how raw marks turn into an A*, A, B, C, D or E, why grade boundaries move from one session to the next, and how the grades on your record shape university applications through UCAS. Everything here is specific to the Cambridge International A Level route (AS + A2), not the older 9–1 style used at earlier stages.

Read them in any order. When you want to put the theory into practice, pair them with our grade calculator, the grade boundary tables, or the grade-to-percentage converter to test your own targets against real figures.
