Flashcards

Key terms and definitions for each topic as flip cards, with spaced repetition saved in your browser. Each card carries what the examiners say about how the term is asked and marked. Definitions are the cheapest marks on the paper, and OCR's mark schemes want the exact wording: every phrase in bold on the card earns part of the mark. Decks for the remaining topics are being written; the define-it drill already covers every real definition question.

How to use them

• Say the answer out loud before you flip. Then be honest with "Knew it" or "Didn't know it": the cards you miss come back every round, the ones you know come back less often.
• A definition that would score full marks in the exam is the target: the term's meaning in one precise sentence, with the quantity (one mole, gaseous atoms, standard conditions) where that is part of the definition.
• "Print all" on any deck gives you paper cards.
