By reviewing often, students should space out their study sessions. Spacing out the frequency of study events, rather than study all content in one large review session (i.e., cramming), information is forgotten to a degree and needs to be relearned. This relearning process is valuable because, although counter intuitive, benefits long-term learning and retention. By spacing study sessions out over time, a student can also prepare for later lectures within a course, by orienting himself with the topics covered in previous lectures which will help him in identifying recurring course themes or concepts. Additionally, studying in a spaced fashion can also keep students engaged during subsequent lectures and assist with identifying important information that they should take notes on while in lecture.
