Inside every session

Everything they need to actually learn it — not just read it.

Each session is built from five connected surfaces, so the same topic gets seen, recalled, tested and applied.

Revision notes

Clear, curriculum‑mapped notes — not a wall of text

Short paragraphs, key terms highlighted, examiner hooks pulled out. Designed to be read in a sitting.

Biology · Photosynthesis
The word equation
Plants take in carbon dioxide and water. Using light energy trapped by chlorophyll, they make glucose and release oxygen.
Exam tip · always mention chlorophyll and light energy together.
Flashcards

Spaced recall, not endless re‑reading

Cards adapt — the ones they got wrong come back sooner. The ones they know slide back.

Explain why a sealed jar of pondweed produces less oxygen in dim light than in bright light.
Look for: mention of light intensity as a limiting factor; reference to rate of photosynthesis; link to oxygen as a product.
