How to make flashcards from your notes
Rewriting your notes feels productive, but reading them again is one of the weakest ways to revise. Turning them into flashcards forces the one thing that works: pulling an answer out of your own head. Here is how to do it well, and the mistakes that make cards useless.
Start from notes you already understand
Flashcards are for remembering things you already understand, not for meeting them the first time. Read the topic through once so it makes sense, then make cards. If a fact still confuses you, a card will just help you memorise your own confusion.
One idea per card
The most common mistake is cramming a whole paragraph onto the back of a card. If the answer has three parts, you will recall one, half-remember the second, and blank on the third, and you will never know which part you actually knew. Split it into three cards.
Front: The causes of World War One. Back: Militarism, alliances, imperialism, nationalism, the assassination of Franz Ferdinand, and the arms race between Britain and Germany.
Front: Which alliance system bound Germany, Austria-Hungary and Italy? Back: The Triple Alliance. Then a separate card for each of the other causes.
Ask a real question, not a prompt to recite
A good front is a question you could be asked in an exam. A weak front is just a heading that invites you to recite everything you know. Compare "Photosynthesis?" with "What two products does the light-dependent stage of photosynthesis produce?" The second has one correct answer you can grade yourself on honestly.
Use your own words on the back
Copying the textbook word for word means you recognise the sentence without understanding it. Write the answer as you would explain it to a friend. If you cannot, that is a sign you do not understand it yet, which is exactly what you want to find out now rather than in the exam.
Turn a page of notes into a deck
- 1Read the page once and underline the facts you would lose marks for not knowing.
- 2For each one, write a question whose answer is that single fact.
- 3Keep answers short. If an answer needs a list, make one card per list item plus one card for how many items there are.
- 4Add a couple of "why" and "how" cards, not just "what" cards. Understanding questions stick better and show up in exams.
If typing every card by hand is the thing stopping you, this is exactly what the Orpheus flashcard generator is for: paste your notes or a photo of them and it writes a first draft of focused cards, which you then edit down. You still decide what matters; it just removes the copying.
Then actually review them
A deck you make and never open is a waste of an evening. The point of cards is repeated testing over days, spaced out so each card comes back just before you would forget it. That is spaced repetition, and it is what turns a deck into a grade.

Build cards by hand or generate a first draft from your notes, then study them with spaced repetition.
Common questions
How many flashcards should I make per topic?
Enough to cover the facts you would lose marks for forgetting, and no more. Twenty sharp cards on one topic beat a hundred vague ones. If a card feels obvious every single time, retire it.
Should I make cards by hand or generate them?
Making them by hand is itself good revision, so do that when you have time. Generating a first draft from your notes saves the copying when you are short on time; either way, edit the cards so each tests one idea.
