If you’re assigned something to read, read it aloud to yourself. This engages not just the internal monologue part of your brain, but speaking and hearing parts, and your brain makes stronger pathways when more senses are engaged and working together.
Don’t buy (eta: or download) flash cards, draw them yourself. This engages sight and abstraction., plus motor skill areas.
Write your own notes, then read them aloud and highlight them yourself. So many parts of your brain make connections by doing this. Don’t just read. That’s not very helpful; you don’t have to study long if you study well.
I think there’s a name for this, but I’m tired and will rely on Cunningham’s whatever.
e: don’t forget about all of your senses – you have way more than 5.
Same principle applies to writing notes by hand vs typing them, for whatever reason people remember things they’ve written significantly better than things they’ve typed.
Writing all over the text you’re reading is also a great way to organize your thoughts! I use Zotero for highlighting and writing notes to myself if I’m reading a bunch of stuff too long to reasonably print.
