For those who haven’t heard of it, I’d totally recommend using Anki. It’s a flashcard program that uses a SRS, or Spaced Repetition System, to get information into your long-term memory. Best of all, the desktop version is completely free, no features barred!
You can even import quizlet decks into it (with pictures!), make it look pretty, etc. etc. It’s transferable across devices with AnkiWeb, and has a free android app and (an unfortunately not free) iPhone app.
I like putting any and all information I wish to recall into it!! Because it’s digital there’s no limit, and the SRS makes sure I don’t end up being totally overwhelmed. All information I wish to recall from classes goes in there, and I generally add more everyday!!
tl;dr Check out Anki, It’s awesome and will help you memorize things
