Section C gives you two extended response questions, each from a different context. You choose one. It is worth 15 marks and you have roughly 40 minutes.
Every one of those questions is built the same way. It names a context, one Area of Study inside that context, and one of the six concepts.
That is the whole architecture. Learn it and the paper stops being a surprise.
What the architecture means in practice
Once you can see the three parts, you can read any Section C question and know immediately what it wants.
The context tells you which of the four areas of the course you are in. The Area of Study narrows it to one specific topic inside that context. The concept decides what kind of argument you have to build.
Two details are worth knowing because they shape your revision.
The question can only be built from the Area of Study column of the syllabus tables, not from the learning objectives sitting beside them. And knowledge of the specific details of research studies is not assessed.
228 questions, or 38 topics turned six ways
There are 38 Areas of Study across the four contexts, and six concepts. That is 228 possible questions.
That number sounds impossible until you notice what it actually is. It is 38 topics, each of which you need to be able to turn six ways.
Which reframes the whole revision problem. You are not preparing 228 essays. You are learning 38 topics well enough that when the question picks a concept, you can say something sharp about that topic through that lens.
Why an accurate content essay can still miss the top bands
The command terms in Section C are AO3 only. Evaluate. Discuss. To what extent.
You will never be asked to describe or outline here. Which means an answer that only explains content cannot reach the top bands however accurate that content is.
This is the trap that catches people who know the psychology well. They write a clear, correct account of the theory, gesture at the concept in the final paragraph, and land in the middle. The knowledge was never the problem. The answer never argued anything.
What "study details are not assessed" actually means
It does not mean studies are useless.
It means the marks come from conceptual understanding and critical thinking, and that a named study is simply the most reliable way to be specific instead of vague.
Nobody is checking your sample size. They are checking whether you can argue.
The practical consequence is about where your hours go. Learning a study to the level of aim, method, finding and what it does or does not establish is worth doing. Learning the year of publication and the exact number of participants is not.
The concept is the part to revise hardest
Anyone can learn a theory. The mark comes from being able to take that theory and say something sharp about causality, or measurement, or responsibility, when the question picks one.
So the useful revision unit is not the topic on its own. It is the topic crossed with each concept.
Take one Area of Study and write one line for each of the six concepts, specific to that content. Not "measurement means how we operationalise things," but what measurement actually makes you question about this topic. What was the construct, what stood in for it, and does the comparison mean what it appears to mean.
Six lines per area, written for that area. That is the work.
Responsibility, the concept most often misused
This one goes wrong more than any other, so it is worth being precise.
In IB Psychology, responsibility is about the consequences of how psychological knowledge is produced and used. Who could be harmed by this research, and who could be harmed by how it gets used.
Research ethics and the application of findings are your main route, and they carry most responsibility questions.
The concept can also reach agency and accountability, but only where that belongs to the psychological argument. If an explanation says behaviour is fixed by genes or by conditioning, asking what that does to a person's responsibility for their own actions is a fair point.
Deciding whether someone deserves blame, on its own, is not.
Two areas, one study, two different essays
Several studies sit under more than one Area of Study, and this creates a specific risk.
Schema theory and environmental influences on cognition both use Loftus and Palmer. Schema theory and cultural factors both use Bartlett. Social learning theory appears in learning and cognition and in human relationships, but the emphasis in each is different.
If you learn one essay per study, you will eventually write the wrong one. In learning and cognition, social learning theory is about learning as a process and the contrast with conditioning. That is a different essay from the human relationships version, even though the evidence overlaps.
So learn which emphasis each area needs, not just which study attaches to it.
Timing and length
Forty minutes. Stronger responses tend to run somewhere between 650 and 800 words, though that is an observed range rather than a target.
Section C is the largest single section of Paper 1, worth 15 of the 35 marks, or about 43%, which is why it gets the largest share of your time. You are also allowed to answer it first if you would rather do the hardest thinking while you are fresh. If you do, cap yourself at 45 minutes and leave space between paragraphs so you can come back and develop it.
How to practise this
Do not write full 15-markers repeatedly. They are expensive and they improve you slowly.
Practise the turn instead. Pick one Area of Study, pick one concept at random, and give yourself five minutes to write the single sharpest paragraph you can that argues something about that topic through that concept. Then pick a different concept and do the same topic again.
Doing that six times on one area teaches you more than one full essay does, because the thing you are actually training is the ability to make a topic yield an argument on demand. That is the skill Section C measures.
Once the turn is reliable, write full timed answers to check that you can hold it for 40 minutes.
If you want every one of the 38 Areas of Study laid out with all six concepts written specifically for that content, the evidence locked to each area, and a note on how the exam could use it, that is what the PsychExcel Section C Content Guide is built to give you.
