Answer:
First, try reading what you're trying memorize out load.
Repeat the information over and over till you understand it.
Try reading and highlighting they key parts and most necessary information.
Rest every 15-20 mints.
Also, associating certain info to certain places, meaning try to connect things you are trying to memorize to things that surround you in your room or wherever you are studying. i think it kind of helps.
