I went to the local library and asked about memory related videos (at that time there were still videos, geez) anyway, I checked out one on Memory Enhancement, can't remember the title exactly, but it taught techniques to remember things visually and believe me it works. It has something to do with the brain and visualizing what you want to remember. I remember drawing little sketches of "ribosome man" and had him doing things in little cartoons I drew for myself, and I made the dean's list while cutting my study time down about half. I also made pre-tests of the material and then I had to "take" my tests. It was boring but it did work. Here's an example of the first technique, I bet you will remember it tomorrow if you hear it today...
you're leaving for work in the morning and the dh says, Oh by the way honey, can you pick up some milk, lettuce, tomatoes, ketchup, mustard and napkins on your way home tonight? Well, you don't need a post-it, you just go out and get in your car and imagine a big head of lettuce bouncing up and down on the hood of the car, with the tomatoes orbiting around it like planets, but the lettuce is splashing mustard and ketchup all over the hood when it bounces, and someone is pouring milk down the windshield, ooh no, there's even napkins stuck in the mess all over the hood.
The more emotional the reaction to the visual, the better you will remember it so it's good to incorporate something that will give you a strong reaction. when i read the above, I get mad cause I love my car and hate to imagine it that way. That reaction will also help me remember!! Humor also works very well. Make super heros out of your biology notes!!
Good luck. Remember we don't use our minds to their fullest potential, mostly because we don't understand how the neurons get connected the quickest. There are techniques that work and they will save you time if you check them out. Good luck!!
