Environment, American education model is similar to domestic high schools, and the learning atmosphere is relatively strong. Moreover, many universities in China are thinking about playing games, picking up girls and skipping classes (a good school will be much better). So, if a student doesn't study and prepare for the exam, do you think the results of exam-oriented teaching can't fail? Because domestic students only care about exams. The exam results speak for themselves. However, tuition fees in American universities are generally based on usual grades, and test scores generally account for about 30% of the total evaluation of learning. In other words, if you study hard at ordinary times, you can pass the exam without taking it (of course, no one fails to take it). And China? Students can only fail if they look at the exam results, so they are usually lazy and think that two weeks of surprise before the exam is enough. Anyway, just pass the exam.
