How can I memorize quicker?

I have many exams coming up in the next few weeks. I need to memorize/revise topics quickly, but I don't know how.

Flash cards are good! And a healthy body is a healthy brain! Eat right and sleep right! When you wake up make sure you have a good breakfast like eggs, or bacon. Protein is good! And snack on something good between meals for snacks like cereal, yogurt or fruit! And they say when you are studying to take a 15 minute break after and hour of studying. If your body is well rested your brain can concentrate on retaining more!

Make index cards with important vocabulary words, dates. names, etc. and just keep flipping through them whenever you have time. Make sure the descriptions aren't too long - just write down the main ideas.

I find flash cards to be extremely effective. Mix up the order. Repeat them over and over and over and over. Recite the info out loud. I find it easier to memorize smaller bits of information at a time, then review everything I've been working on.

For instance, I'm learning a new language now. I have vocabulary flash cards. I work on 4 new words a day. I recite each one 21 times or more. I carry those 4 cards with me during the day and review them when I get a chance. At night I quiz myself on the new words, then quiz myself on the whole stack of cards I've already memorized. If I miss one, it goes back into the pile of 4 cards to study the next day.
