Math technique, learning science, and UEC exam prep.
Spreading effort evenly across chapters loses marks on the topics that matter. A breakdown of SC04–SC07 topic frequency and weighting.
Read more →The forgetting curve is blunt: doing questions is not the same as remembering them. Spaced repetition is the one research-backed fix, and here is how to use it.
Read more →We had 500 SC06 structured questions graded blind by 3 teachers and by DuckMath AI, comparing accuracy, speed and step-level analysis. The result surprised us.
Read more →Chain rule, quotient-rule signs, + C, integral limits, area sign, stationary-point classification — most calculus marks are lost in these six spots, and it is checking, not knowledge, that fails. With a pre-exam checklist.
Read more →Work one side only, convert everything to sin and cos, know the core identities cold, or squeeze both sides to a common form — four reliable ways into an identity proof when you are stuck, with a must-memorise list.
Read more →Scan the whole paper first, a minute per MCQ, method marks on every structured question, ten minutes to check — a time plan that keeps one hard question from sinking your paper.
Read more →SC04 tests "can you do this method"; SC06 tests "which method, and how do they connect." The real gap, what SC05 bridges, and a four-week catch-up plan.
Read more →Copying is not analysing. Sort mistakes into concept / calculation / reading / time, ask three questions per mistake, and revisit on a forgetting-curve schedule — an error log that actually works.
