Flashcards are really useful to study! Although this is gonna discuss how to make flashcards well, the most important thing is actually making the flashcards! The process of writing the information down on flashcards will actually help a lot with studying, which is more than half the battle. So, my first advice is to use pen and paper. You can cut up a normal piece of paper to smaller sizes if you want or use index cards, but doing it on physical paper is much better for memory than online tools or printing something out.
I’ve found that flashcards work best when they have a little bit of information on both sides of them. Don’t write whole paragraphs or lots of details. I’ve used them a lot to study things like other languages, and having them for individual words and smaller things works better for me than for full sentences. It also breaks everything up into tasks that can be done quickly.
You can make them look pretty if it helps you with them, such as making their letting look nice, but this shouldn’t be your primary focus.
Finally, when using flashcards, you should focus on what you’re weakest at. Put more emphasis on what you get wrong rather than what you get right! It’ll help make sure that your weak points get better, even if it hurts a lot to keep forgetting things. Also, it’s best to keep using your flashcards over a longer amount of time rather than trying to cram everything into one day for your long term recall.
