Concept

Learn the idea before you practise

Concept gives each syllabus point a clear explanation first: definition, worked example, common mistake and exam link. Use it before practice, or after a missed mark points to a weak idea.

Common questions

Are Concept pages the same as ordinary notes?

No. Concept pages explain the idea, show how it appears in exams, and link you back into practice.

Can Concept help with definitions?

Yes. Definitions, examples and common exam mistakes are exactly the kind of content that makes concept pages useful.

When should I use Concept instead of Question Bank?

Use Concept before practice when an idea is unclear, or after practice when a missed mark points to a weak explanation.
