Key examiner messages
Top priorities from the principal examiner before you revise
A significant portion of your marks (≈35% \approx 35\% ≈35%) lies in AO2 (Application).
In Paper 1, scenarios featuring characters like Maddie (depression) and Lukas (synoptic behavior) are not mere background context; they are the bedrock of your response.
Marks are consistently won by students who use specific scenario details to anchor psychological concepts.
Conversely, marks are lost when candidates write generic textbook answers without direct reference to the stimulus.In Paper 2, Section A (Research Methods) accounts for a massive 37 marks.

Command word playbook
How to match each command word to the expected response style
Give reasons and link mechanism to outcome; each point needs a because/so chain.
State features in sequence or list observable properties — do not explain causes unless asked.
Show formula, substitution, and unit; method marks need visible working.
Match the expected response style for “Assess” questions.
Match the expected response style for “State” questions.
Match the expected response style for “Define” questions.
Name or point to the specific feature asked for — avoid extra explanation.
Weigh arguments for and against with evidence; end with a supported judgement.

Session analysis
A significant portion of your marks (≈35% \approx 35\% ≈35%) lies in AO2 (Application). In Paper 1, scenarios featuring characters like Maddie (depression) and Lukas (synoptic behavior) are not mere background context; they are the bedrock of your response. Marks are consistently won by students who use specific scenario details to anchor psychological concepts. Conversely, marks are lost when candidates write generic textbook answers without direct reference to the stimulus.In Paper 2, Section A (Research Methods) accounts for a massive 37 marks. Simple calculations—such as percentage changes, ranges, and simplifying ratios (e.g., reducing 56:100 56:100 56:100 to 14:25 14:25 14:25)—are easy wins if you show your working. Failing to write down intermediate steps is a critical error that costs easy marks.

Examiner notes & key calculations
- The 'Half-Linked' Evaluation: In 4-mark 'Explain' questions (such as Q11 on the strengths and weaknesses of prison), examiners report that candidates often identify a valid point but fail to provide a linked justification that relates directly to the case study (e.g., Calvin's driving offense).
- Isolating Synoptic Areas: In Q23 (Lukas's musical behavior), many students analyzed memory and social conformity as separate, disconnected essays. To reach Level 3 (7–9 marks), you must actively synthesize these fields to build a cohesive explanation.
- Amnesia Confusion: A recurring misconception is mixing up retrograde amnesia with anterograde amnesia, leading to inverted explanations of Ivana's test results.
