1) GRAPH OR DOTTED PAPER
I don't know if you can really see, but you can find dotted notebooks in Japanese dollar stores, or anywhere else. You can also buy it online, but you can find graphing paper anywhere. I find it easier to keep your notes organized and more clean because you have lines, or dots, to track what you are writing.
2) COLOR CODE
If you color code things (make sure to make a little key at the top so you know what colors associate with what topic), you will be organized and you can reference to your key while you're studying.
3) FLASH CARD = BINDER RINGS
You will need:
Studying flash cards
Take a couple of cards at a time, and hole punch it at the corner. Take a binder ring, and put it through the holes. That way, you have all of your cards in one place, and they will never get lost. If you want to rearrange the order of the cards, you can unclip it!
