10 topics · specification 7408 · explanations and examiner marking in AQA’s own language
This is the full AQA A-Level Physics specification, code 7408, as elid holds it — 10 topics, each with the terminology AQA marks against. Every explanation and every mark elid gives you is written against this list, not a generic A-level one, because the same question answered in CAIE, Edexcel or OCR language loses marks it should have earned.
Use of SI units, prefixes, limitations of physical measurements, scientific notation, estimation, random and systematic errors, precision, accuracy, resolution, absolute, fractional and percentage uncertainties.

Paste an answer you have written and elid marks it point by point against the AQA scheme: which marking points you hit, which you missed, and the sentence that would have earned each missing one. It is the difference between being told an answer is “good” and being told exactly where the marks went.
