How to Answer 16-Mark Questions in A-Level Psychology

The mark split, the plan and the paragraph structure behind a real 16/16 answer from a June 2026 AQA script.

By Mr K · Holder of the world’s highest A-Level Psychology exam result (100%)

Sixteen-mark questions decide A-Level Psychology grades. On the June 2026 Paper 1, three of them carried 48 of the 96 marks. Across Papers 1 and 2, they cost three students 53 of the 142 marks those students lost between them.

Most of those marks were not lost on knowledge. They were lost on construction. This guide sets out the structure of a real 16/16 answer so that you can copy the structure, not the content.

Step 1: Know what the 16 marks are made of

Every 16-mark question is split across assessment objectives, and the split depends on the question type. Check which one you have before you write anything.

Two points follow from the table. First, on a compare question the outline earns the AO1 only, so outline the first topic and spend everything else on the comparison, where all ten AO3 marks sit. Second, AO3 is worth as much as AO1 or more in every type, which is why a long description with a thin evaluation stalls in the middle levels.

Command words matter here. Describe and outline earn AO1. Discuss, evaluate and compare all demand AO3.

Step 2: Understand how the examiner marks it

A 16-mark answer is not marked by counting points. The examiner reads the whole answer, places it in a level using a best-fit judgement, and then chooses a mark within that level. The top level (13 to 16 marks) rewards:

• accurate, generally well-detailed knowledge;
• thorough and effective discussion;
• on a stem question, application that is appropriate and where the links between theory and stem are explained;
• a clear, coherent, focused answer with specialist terminology used effectively.

Accuracy is a gate. Even occasional inaccuracies can stop an otherwise good answer reaching the top level. One student wrote that Clive Wearing’s long-term memory was intact. The examiner crossed it out twice, and because that case study was the lead strength, the whole evaluation paragraph built on it collapsed. A wrong study does not lose you the study. It loses you the paragraph.

Step 3: Plan in two minutes

A 2-hour paper with 96 marks gives you roughly 1.25 minutes per mark, so about 20 minutes for a 16-marker. Spend the first two on a plan. The student who scored 16/16 on a resistance to social influence question planned in three columns, then wrote the essay in exactly that order. His plan, abbreviated:

A different student on a different script planned a strength, crossed it out, and wrote three limitations with no strength. She scored 8/16. A plan you depart from is worse than no plan, because you spent the time and lost the benefit. Write the plan, then tick each item off as it goes into the answer.

Step 4: Give every paragraph one job

The 16/16 answer had seven paragraphs, each with a single job, and the examiner’s tags landed one per paragraph:

1. AO1: first explanation, with its own evidence (Knowledge).
2. AO1: second explanation, with its own evidence (Knowledge).
3. AO2: the first character in the stem (Application).
4. AO2: the second character in the stem (Application).
5. AO3: a strength (Discussion).
6. AO3: a limitation (Discussion).
7. AO3: a different kind of limitation (Discussion).

The structure made it easy for the examiner to place every sentence. Without a stem, drop the two AO2 paragraphs and give that space to AO3, where you will typically be able to develop three or four distinct points.

Notice what is missing: padding. Fewer, fully developed paragraphs outscore a long list of thin ones.

Step 5: Write each AO3 paragraph as Point, Evidence, Explain, SO

The AO3 block is the largest and the one students handle worst. In the June 2026 evidence, evaluation failed in the same few ways. The fix is a four-part paragraph:

The SO statement is the “so what”. It must say something the first three parts did not, and it must close on the question’s own wording. Examiners name this exact step: point, then evidence, then explanation, then why it matters. In the 16/16 answer every paragraph ended on a consequence, for example “the social support explanation can be praised as a valid explanation of resistance to social influence” and, on the limitation, that the research “may be unapplicable in explainng conformity and obedient behaviours for women”. The typos cost nothing.

Make each point a different kind of argument

That answer used three AO3 points doing three different jobs: empirical support, a methodological limitation (an artificial laboratory task), and a sampling limitation (all-male samples). Compare students who wrote two limitations that were the same argument, norms changing over time and norms changing across cultures, and were told “Evaluation is limited in effectiveness.” Before you write point two, ask what kind of argument point one was, and make point two a different kind.

Step 6: On a stem question, quote it and explain the mechanism

Application earns credit where content is fastened to something specific in the stem, never on the definition. The 16/16 student did not stop at labelling the character:

“this shows that Ali believes he is in charge of his own behavior and destiny, as he feels free to make his own decisions, such as deciding not to conform to incorrect answers in the line length task, and that external influences such as the large group of confederate participants who all gave the same incorrect answer, do not influene his decisions…”APPLICATION Mechanism explained, tied to the stem

Position matters too. Another student wrote all her application in a single paragraph on the supplementary answer book, after everything else, and scored 12/16. On a stem question AO2 is worth 4 marks and the examiner has to find it. Put it in the middle of the essay in clearly signposted paragraphs, one per character.

Step 7: Avoid the five mistakes that cap 16-markers
