Writing and rewriting class notes is potentially the most effective method for learning course material. I like to use different colored sharpies to make my notes fun and easy to read. I prefer to use red for headlines, blue for sub headlines, and green for the notes that fall under each headline.
If you are taking a class like medical terminology, you may use one color for each drug group. I would rather rewrite my notes with a pencil over typing my notes because you learn about three times faster by manually writing them.
It has been highly documented and suggested that you forget a lot of what you type because many people type faster than what they can have a chance to memorize. I highly recommend that you you speak the notes out loud as you write them to commit them to memory even faster.
It is a good idea to rewrite your notes 2-3 times for good retention of the material. You should have a really good overall idea of what the subject matter was about by the time you are finished. This method works fantastic for when you are going to have a test over 20 or more pages of notes.
The final recommendation that I can make is that you rewrite the notes in the same area that you are having the test if possible and while chewing gum. On test day you will have the advantage of chewing gum at the same place that you have rewritten all of your notes, time and time again. The chewing gum method is a great strategy for helping you to recall information that you had in your mind while chewing gum last.
If the room and gum strategy is not possible, you may divide your notes into three sections or more. Rewrite each section in a different room then rewrite that one section in the same room every time. Devote one room to science, one to math, one to English. This may help you recall information during the test for the subject matter you are testing over.
