Every wrong answer hides a reason.
PinPoint names it.
It turns your syllabus into exam-style questions that pinpoint the exact misconception behind each mistake, then bring it back until it's fixed. Built for IGCSE, IB and A-Level science.
11,000+ questions · 3,650+ syllabus points · free while in beta
Re-reading notes and highlighting feelproductive, but they hide the things you don't actually understand. You only find those gaps in the exam, when it's too late. PinPoint surfaces them now, one question at a time.
How it works
One idea at a time
Every question is a hinge question that tests a single concept, so you always know exactly what you got right or wrong.
It names your misconception
Each wrong answer maps to a specific, named misconception, so you see precisely where your thinking went off.
It corrects it on the spot
A short correction step targets the exact mistake you made, so every wrong answer actually teaches you something.
It repeats until it sticks
Spaced repetition brings each weak point back at the right moment, until every syllabus statement turns green.
Every wrong answer shows you what to fix
Get a question wrong and you find out the misconception behind it, not just what the right answer was.
Works on phone & laptop · Proper equations & diagrams · Private by design · No ads, ever
It is good for learning everything in the syllabus, especially the things that are often not covered during class- or only covered for a short amount of time.
What you can revise
Built syllabus statement by syllabus statement. Pick your qualification, then your subject.
Prefer a tutor alongside it?
PinPoint tutoring runs every session on the platform, so your tutor already knows exactly what you keep getting wrong before the first lesson, and every session is spent teaching from the start.
