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.

Mistakes

  • The defining characteristic of the OCR AS Level Chemistry B (Salters) specification is its context-led design. Unlike traditional specifications, you will rarely face questions presented in isolation. Instead, concepts are embedded in real-world scenarios, such as analyzing the purity of local table salt alternatives ("Lo Salt"), optimizing industrial systems like the Cativa or Monsanto processes, or studying stratospheric ozone dynamics. The most common mistake candidates make is falling into the "storyline trap"—getting so absorbed in the context that they lose sight of the core chemical principles being tested.
