In fact, it can't be said that this cramming method is not good, but it is better than the one that doesn't study at ordinary times and doesn't panic in the exam. As our teacher used to say, it is difficult to get a gun when you get cold feet. For those who study hard at ordinary times, reviewing before the exam can be well consolidated. For those who don't study hard at ordinary times, cramming is a good way to memorize temporarily, and they can only cope with temporary exams. However, you don't have a solid grasp of its knowledge points, and it's easy to forget if you don't review much later, so if you want to really learn professional knowledge, you should study hard at ordinary times and cram for the exam temporarily.
