After about 15 minutes, your ability to remember what you read lessens

Are you curious about the best way to memorize or remember what you study/read? Make note cards only for stuff you do not remember. One of the most interesting things that my smart classmates did was that they read a couple of note cards every day without fail. Some had them stuck to their door, others had them in a folder on their desk and again others had them in a flip-book on their dinner table so they would see them as often as possible.
