In education, cramming (also known as mugging or swotting, from swot, akin to "sweat", meaning "to study with determination") is the practice of working intensively to absorb large volumes of informational material in short amounts of time. It is often done by students in preparation for upcoming exams, especially at the last minute. Cramming is often discouraged by educators because the hurried coverage of material tends to result in poor long-term retention of material, a phenomenon often referred to as spacing effect.
Cramming is often done the night before an exam.
Cramming as a study technique
H.E. Gorst stated in his book, 'The Curse of Education', “as long as education is synonymous with cramming on an organized plan, it will continue to produce mediocrity.” 
Generally considered as a negative study technique, cramming is becoming more and more common among students both at the secondary and post-secondary level. Pressure to perform well in the classroom and engage in extracurricular activities in addition to other responsibilities often results in the cramming method of studying. Cramming is a widely used study skill performed in preparation for an examination or other performance-based assessment.
Most common among high school and college-aged students, cramming is often used as a means of memorizing large amounts of information in a short amount of time. Students are often forced to cram after improper time utilization or in efforts to understand information shortly before being tested. Improper time management is usually the cause for last-minute cramming sessions, and many study techniques have been developed to help students succeed instead of cramming.
Cramming and school performance
Teaching students to avoid last-minute cramming is a large area of concern for education professionals and profit for educational corporations and businesses. Learning and teaching study techniques that enhance retention as opposed to learning for a single examination is one of the core issues that plagues colleges and university academic advisors, and also adds to the stress of academic success for students. Ideally, proper study skills need to be introduced and practiced as early as possible in order for students to effectively learn positive study mechanisms.
According to W.G. Sommer, students in a university system often adapt to the time-constraints that are placed upon them in college, and often use cramming to perform well on tests. In his article, Procrastination and Cramming: How Adept Students Ace the System, he states “Many students outwardly adapt to this system, however, engage in an intense and private ritual that comprises five aspects: calculated procrastination, preparatory anxiety, climactic cramming, nick-of-time deadline-making, and a secret, if often uncelebrated, victory. These adept students often find it difficult to admit others into their efficient program of academic survival.”
Active learning and critical thinking are two methods which emphasize the retention of material through the use of class discussions, study groups and individual thinking. Each has been cited as a more effective means of learning and retaining information as compared to cramming and memorization. On the other hand cramming suits better to the sciolistic knowledge actually required by the academic examination method.
