Recall Drills

Type each answer from memory, then check it against the mark scheme — retrieval practice that fixes recall far better than flipping a card. Available on every flashcard deck.

Mole Calculations

Every amount-of-substance equation on one page — mass, concentration, gas volumes, the ideal-gas equation, percentage yield and atom economy — with a tap-to-reveal recall drill.

Calculations (self-mark)

The AQA Chemistry calculations that lose the most marks — GCSE moles, titration, reacting masses, % yield and atom economy, plus A-level Kc, pH, calorimetry and the ideal gas equation — each a worked exam question you mark against a real C1/M1/A1 scheme.

Mole Calculation Trainer

Drill mole calculations against the clock — moles from mass, mass from moles and concentration, with real molar masses and instant marking.

GCSE Identification Tests

Flame tests, precipitates and gas tests — the whole GCSE qualitative-analysis topic on one page, with a tap-to-reveal test mode.

Flashcards

460+ spec-point chemistry cards with spaced-repetition review — flip, self-grade, and they come back the day you'd start to forget them.

Required Practical Hubs

The eight AQA required practicals on one page each — apparatus, method, variables, the expected results, and the marks examiners report students losing.

Key Definitions

The AQA GCSE Chemistry definitions marked to the word — bonding, moles, rates, acids and electrolysis — with a tap-to-reveal test-yourself mode.

Blurt Frameworks

Cover the page, write everything you know about a Paper 1 topic, then reveal a spec-accurate scaffold and tick off what you remembered — retrieval practice that shows you exactly what's left to revise.

6-Marker Trainer

The AQA GCSE Chemistry extended-response questions students lose most marks on — plan your answer, self-mark against the level-of-response descriptors and indicative content, then read a model Level 3.
