Key examiner messages
Top priorities from the principal examiner before you revise
The January 2025 series for IAL Psychology presents a moderately challenging hurdle for students, primarily due to the heavy integration of Research Methods (AO2/AO3 skills) and complex mathematical calculations across both Unit 1 and Unit 2.
While the recall elements of core theories (such as the Multi-Store Model and Social Learning Theory) are accessible, the application and extended evaluation questions demand high-level analytical skills.

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.
Weigh arguments for and against with evidence; end with a supported judgement.
Match the expected response style for “State” questions.
Match the expected response style for “Assess” questions.
Present multiple perspectives with evidence; balance breadth and depth.
Match the expected response style for “extent” questions.

Difficulty Verdict
The January 2025 series for IAL Psychology presents a moderately challenging hurdle for students, primarily due to the heavy integration of Research Methods (AO2/AO3 skills) and complex mathematical calculations across both Unit 1 and Unit 2. While the recall elements of core theories (such as the Multi-Store Model and Social Learning Theory) are accessible, the application and extended evaluation questions demand high-level analytical skills.
Where the Marks Are
A staggering portion of the total credit across these units rests on Psychological Skills. Between statistical calculations (Spearman's Rank, ratios, percentages), drawing bar charts, and explaining practical investigation designs, students who treat research methods as a minor sub-topic will severely limit their grade potential. Additionally, high-mark essays (the 12-mark evaluation of Bartlett and the 16-mark synoptic essay on Benjamin's behaviour) make up a significant portion of the total paper weighting.
Examiner notes & key calculations
- Hypothesis Operationalisation: Students often lose easy marks by failing to operationalise both variables completely. Simply stating 'exercise' and 'sleep' is insufficient; they must specify 'average hours of exercise per week' and 'average hours of sleep per night'.
- Mathematical Rounding & Simplification: Ratios not converted to their lowest terms (e.g., in Q9b) or incomplete working out in the Spearman's rank table are common areas of dropped marks.
- Generic Essay Blocks: In the 16-marker (Q12) and 12-markers (Q11), candidates frequently copy-paste generic evaluation points without weaving in the specific details of the scenario (e.g., Benjamin's aggression at home versus at the theatre) or the specific methodology of the chosen study.
