A topic can be studied in two ways: spaced repetition, which is what Memorics does unless you ask for something else, and practice.
Spaced repetition
Spaced repetition asks you a card again just before you would forget it. Each time you remember it, the next review comes a little later, so the cards you know well take up less and less of your time and you spend it on the ones you don’t.
A session of spaced repetition studies the cards that are due, and some new cards: up to 20 a day for a topic unless you choose otherwise. After each card, say how it went with Again, Hard, Good or Easy. Each button shows when you’ll see the card again if you choose it.
A new card needs Good twice in a row before it’s done for the day. A card you’re reviewing needs it once, unless you forget it and press Again.
Practice
Practice goes over every card of a topic until you’ve answered each right twice in a row, with only Again and Good. It never changes when a card is due, so you can use it as often as you like:
- the night before an exam, to go over everything once more
- on a topic you’ve just made, before any cards are due
- on only the cards you flagged
- after a session, on the cards you missed
Which one to use
Use spaced repetition every day. It’s what makes you remember things for months, not only until the exam, and it’s what your day’s session does.
Use practice when you want to go over a topic now, whether or not its cards are due. If you have an exam coming, add it under Exams instead of practicing a lot right before it: the exam’s plan spreads the work over the days before it, which works much better than cramming at the end.
