How do you answer the AO3 source questions, judging an ancient source for its usefulness to an enquiry?
The AO3 source skills: making supported inferences from a source, comparing two sources, and judging how useful a source is for a stated enquiry using content, provenance (nature, origin and purpose) and contextual knowledge, rather than labelling a source reliable or biased.

What this dot point is asking
The AO3 source skills are the heart of an ancient-history GCSE. This page teaches the transferable method for the three kinds of source question: making supported inferences from a source, comparing two sources, and judging how useful a source is for a stated enquiry, using its content, its provenance (nature, origin and purpose) and your contextual knowledge. The method applies equally to Herodotus, Livy, Polybius, an inscription, a relief or a coin.
The answer
The three kinds of source question
Inference: go beyond the surface
Content, provenance and context
Content alone is not evaluation: a top answer uses content as the start and then judges value through provenance and context.
Utility, not reliability
You then judge how useful the source is for the exact enquiry, turning its limitations into evidence rather than a reason to dismiss it.
Examples in context
A model answer never stops at "this source is biased": it explains what the bias makes the source valuable for, the move that lifts an answer to the top.
Try this
Q1. What three things do you use to judge an ancient source's usefulness for an enquiry? [Knowledge recall]
- Cue. Its content, its provenance (nature, origin and purpose), and your own contextual knowledge.
Q2. Explain why a propaganda source can be very useful despite its bias. [Short source evaluation]
- Cue. Because propaganda is the best evidence of the ideology and self-image its maker wished to project, precisely because of its purpose, so it is highly useful for an enquiry into that ideology, even though it is not a neutral record of events.

OCR J198 20208 marksHow useful is a named ancient source for understanding a stated enquiry? [generic AO3 'how useful' question, shown at the 8-mark depth-study style]Show worked answer →
A generic AO3 source-utility question, transferable to any topic.
Method. Start with content (what the source reveals about the enquiry), weigh the provenance (nature, origin and purpose, which makes it valuable for some questions and limited for others), test against your contextual knowledge, and judge usefulness for the specific enquiry.
Example move. A royal inscription such as the Cyrus Cylinder or Behistun is highly valuable for official ideology precisely because it is propaganda; a careful historian such as Polybius is valuable for analysis. The top level judges value for the question, not reliability in the abstract.
OCR J198 20225 marksStudy a source. What can you learn from it about a stated enquiry? [generic AO3 source-inference question, shown at the 5-mark style]Show worked answer →
A generic AO3 source-inference question, shown at the 5-mark style.
Method. Make two or three supported inferences: state what the source suggests about the enquiry, and back each with a detail from the source.
Watch the trap. Do not merely describe or copy the source; an inference goes beyond the surface to say what the source shows. The top level makes developed, supported inferences linked to the enquiry.
