Master every GCSE calculation, one rung at a time. Learn the skill, see it worked, then do one yourself — nail it to unlock the next. Pick your science:
From reading Ar off the periodic table up to titration calculations.
13 rungs · built-in periodic tablePick the right equation, substitute, rearrange — motion up to Higher & Triple-only.
19 rungs · built-in equations sheetData, microscopy, rates, ecology and genetics — the maths behind biology.
10 rungsEvery practical question on the paper comes down to the same handful of skills: what was changed, what was measured, what had to stay the same — and whether you can trust the numbers at the end. Learn the skill, see it worked, do one together, then finish on a real exam question. Pick a strand:
Independent, dependent and control variables, hypotheses, data types and results tables — the foundation of every practical question.
Choosing apparatus with the right resolution, stating resolution, hazards and control measures, why you repeat, and improvements that actually fix the fault.
Anomalies, means without them, accurate vs precise, repeatable vs reproducible, and whether a conclusion is actually valid.

Low % with many attempts = genuinely hard (teaching gold). Low % with a few attempts = check the question.
