AO1/AO2 · First chain
Build an evidence-to-impact chain for the named factor.
AQA 8145 · AO1/AO2 · Germany causal judgment
Causal judgment: two good chains, no comparison
The comparison mark. Credit at the highest level requires the factors weighed against an explicit criterion, and a counterargument tested rather than ignored.

The lost mark
One answer. Several places the method can fail.
Studara does not reduce the response to right or wrong. The reviewed contract checks these states independently.
AO1/AO2 · Second chain
Build an equally developed chain for the competing factor.
AO2 · Compare and test
Weigh them against an explicit criterion and test the strongest counterargument.
Why it goes wrong
The diagnosis stays uncertainty-safe.
A wrong response can support a specific measured diagnosis. A blind multiple-choice diagnostic records only a possible cause until later working provides stronger evidence.
01
The error
Building two strong evidence-to-impact chains and then asserting that one mattered more, with no criterion stated for the comparison.
02
Why it survives revision
Each chain, read on its own, is genuinely strong — and each one is the thing that was practised. The mark being missed is not inside either chain; it is the relationship between them, which is the one part that was never separately rehearsed.
The worked repair
Repair the smallest broken step.
Teaching is not evidence. This one move is the repair; the proof checks begin after it disappears.
Name the criterion — timing, necessity, scale — compare the factors against it, then test the strongest counterargument.
What happens after the repair
Correction is the start, not the result.
Immediate
Asked again straight away, on a different question
The repair leaves the screen and a new authored item checks the method unassisted. Being taught something is never evidence that it was learned, so this is the first stage that counts at all.
Delayed
Asked again after at least 1 day
A parallel form of the same method, unassisted, with the repair no longer on screen. A retest in the same session does not count.
Transfer
Asked again when the surface changes
The transfer form names a different factor in the question, so the comparison has to be rebuilt rather than recalled.
Exam
Asked again under exam conditions
Timed, carrying the mark tariff, in an exam-like response format and aligned to the specification. Any one of those missing and the evidence is refused.
REVIEWED BOUNDARY
This page covers one reviewed family: AO1/AO2 · Germany causal judgment. Build two evidence-to-impact chains, compare them with an explicit criterion, test a counterargument, and reach a supported verdict—without inferring an official examiner level. Other families within the same GCSE History topic are outside this reviewed journey, and Studara does not apply the proof label to material that has not been reviewed. No grade-uplift claim is made anywhere on this site.
Straight answers
Before you use this guide.
How do I reach the top band on a 'how far do you agree' question?
Explaining two factors well is not enough — the highest band needs them compared against a stated criterion, such as timing, necessity or scale, with a counterargument addressed.
What counts as a criterion for comparison?
Anything that makes the comparison measurable rather than asserted: which factor came first, which was necessary for the other, or which affected more people.
Does Studara guarantee a higher grade?
No. Studara has not run a controlled outcome study and publishes no grade-uplift claim. What has been measured, what is withheld, and the metric that failed its bar are all on the public evidence page.
