The term 'cause of cramming' can be summarized as a TEST, which is a four letter word. Cramming is a common practice among students who are preparing for tests or exams. It involves studying large amounts of material in a short period of time, often the night before the TEST. Cramming can be caused by procrastination, lack of preparation, or lack of understanding of the material. It can also be caused by a lack of time management skills or an inability to focus on the material. Ultimately, cramming can lead to poor TEST performance and can be detrimental to a student's academic success.
