Both specifications are explicit: candidates sit these papers without a calculator and without a formulae booklet. That turns every relationship on the syllabus into a memorisation liability, and it makes one question worth answering before you start memorising - which ones actually come up?
We tagged 1,250 real past-paper questions to find out. The sheet lists all 695 entries across the seven modules - every formula, rule, definition and technique - each tied to the specification clause that requires it, with the variables, the equivalent forms and the mistakes that actually cost marks. ESAT physics additionally carries a measured frequency against each entry, because physics is the module we have tagged formula by formula so far; the other six are ranked by topic rather than by entry.
A sample of what is inside
The ten physics relationships that earned their place.
Ranked by the share of 193 tagged ESAT physics questions that could not be solved without them. These percentages do not add up - one question often needs several formulae.
