Calculator policy
A scientific or graphical calculator that meets JCQ regulations may be used (some GCSE Mathematics and Science papers are non-calculator). Graphical calculators must be set to exam mode; you must clear any stored programs, notes or data before the exam, and the calculator must not be able to retrieve stored text or formulae.

- In AQA AS Physics, the difference between an A grade and a C grade often isn't the complex physics theory—it is basic unit consistency. Examiners routinely report that thousands of marks are dropped every year because candidates plug raw numbers directly from the question into their equations. For example, if a cable's cross-sectional area is given in mm2 ^2 mm2 or an extension in millimetres, you must convert these to SI base units (m2 ^2 m2 and m m) first. Neglecting millisecond (ms ms) time intervals or microamperes (μA \mu μA) in current calculations leads to catastrophic power-of-ten errors that void accuracy marks instantly.
