Flashcards: lock in the key ideas
You will be able to: Recall the eight key facts of Module 2 from memory, and keep them with short spaced reviews.
Same system as Module 1: answer in your head first, then flip, and be honest with "Again" and "Got it". Cards you know come back after 1, 3, 7 and then 14 days; a card you miss comes back again today. Your Module 1 cards stay in the deck.
Tip: come back tomorrow. Only the cards that are due will show, so the review will be short.
