Article in English: Though reading, and rereading, lectures in a short time frame (often the day before the exam) is common practice, research has shown it is a very ineffective study strategy. Your mind is not, after all, a video recorder. Nonetheless, reading each set of lecture notes more than once is still very helpful, if done correctly. There are two ways to get the most benefit from reviewing your notes: spacing the time between studying and mixing up study topics.  Space out the time between studying each set of lecture notes. For example, read over your notes within 24 hours of taking them. If you do this, you will retain approximately 50% of the material. If you wait longer than 24 hours, however, you will only retain about 20% of the material. Then wait another week or two to read that lecture's notes again and so forth. While waiting to reread might sound counterintuitive (Won’t you forget a lot by waiting, after all?), cognitive psychologists have found that the closer you are to forgetting the material, the more you will cement the information to your long-term memory through the process of re-exposure and remembering.  Additionally, read your notes aloud. This converts a passive activity into an active one and creates auditory links in your memory pathways.  Mix up the topics you study. Let’s say you’ve set aside two hours of studying per day. Instead of spending an entire study session studying your notes from one class, spend a ½ hour studying one subject, a ½ hour studying another subject, and then repeat. Mixing up topics in this way (interleaving) requires a type of information reloading that forces your brain to notice similarities and differences – a higher order of information processing that leads to greater comprehension and long-term retention. Part of this study technique’s modus operandi is that as soon as you begin to feel like you really know the material, you need to switch it up and work on something else for awhile. So put away that blue notebook and pull out the red one. The same day as you take...
