  2. “Describe …” — sequence the main features without evaluation. Reward: accuracy and completeness.
  3. “Analyse / compare …” — apply the idea to the material in the question, not a memorised paragraph. Reward: application.
  4. “Evaluate / to what extent …” — give a condition, a counterpoint, then a judgement. Reward: a weighed conclusion.

Common mistakes students make

  • Mixing boards — Edexcel A Level (9PS0) is not interchangeable with another Psychology programme.
  • Describing when asked to explain — features without a mechanism score the lower tariff only.
  • Vague definitions that do not use specification language.
  • Skipping the neighbouring subtopic in Criminological Psychology Methods, so the paper feels like isolated facts.
  • Never testing retrieval — notes feel fluent until the free Issues Of Reliability, Validity, Objectivity, Credibility And Ethics In Research quiz shows the gap.
