Common mistakes
Misidentifying Section B
Labeling Section B as Social or Cognitive psychology.
Fix itSection B is specifically the biopsychology section and should be identified as such in all answers.
Confusing Section Names
Students often mix up the names of the Paper 2 sections, writing that Section C is about psychological approaches instead of research methods.
Fix itUse the exact wording from the specification: Section C – Research Methods. Re‑check the paper outline before answering to avoid this error.
Misunderstanding the length of short answer questions
Assuming short answer requires a paragraph.
Fix itShort answer questions are usually 1–2 sentences and carry 1 mark.
Misjudging Paper 3’s weight
Assuming Paper 3 is worth 50 % of the A‑level instead of 33.3 %.
Fix itRemember that Paper 3 contributes one third of the total mark, not half.
Treating Section A as optional
Assuming students can skip Section A or that it is not essential for the final grade.
Fix itSection A is compulsory and accounts for 24 marks; all candidates must answer its questions.
Confusing correlation with causation
Assuming that a correlation between attachment style and relationship satisfaction proves a causal link.
Fix itExplain that correlation does not imply causation; experimental manipulation or longitudinal data are required to infer causality.
Choosing more than one topic from Option 2
Students sometimes attempt to answer questions on multiple topics from Option 2.
Fix itOnly one topic may be selected; attempting to cover more than one will result in a loss of marks.
Confusing aggression with violence
Students often equate aggression with violence, ignoring non‑violent forms such as verbal or relational aggression.
Fix itClarify that aggression includes a spectrum of behaviours, from verbal threats to physical harm, and that violence is only one manifestation.
Assuming Paper 3 is identical to Paper 1
Students often treat Paper 3 as a repetition of Paper 1, overlooking the inclusion of extended writing.
Fix itReview the specification to confirm that Paper 3 contains all three question types and plan revision accordingly.
