1. Help us review what we have learned in class: Some students think it is unnecessary to leave homework, but on the contrary, without homework, I don't think a large number of students in the university will take the initiative to review what they have learned in class after class. Most students will choose to lie flat in the dormitory or go shopping, and a few students will choose to go to the library to read some extracurricular books that they are interested in. If they don't leave their homework, then Saturday and Sunday will be wasted. In fact, even if the university leaves homework, it doesn't stay every day, because all the subjects in the university are not available every day, so they usually stay once a week, so the students' homework pressure is not great.
2. Help us to test the mastery of knowledge in the classroom: Most teachers in universities don't explain directly according to the handouts in textbooks, because universities are more professional and teachers are also professional teachers, so when teachers give lectures, they will expand the relevant practical experience or examples that teachers know to help students master knowledge points, but there are still many courses in universities, and even some knowledge points have a certain depth. So sometimes we can't master all the contents of a class, so one of the functions of homework is to test our mastery of the knowledge in class and where we have mastered it, so that we can focus on reviewing or re-learning when reviewing.
3. Provide a key direction for our subject final exam: The final exam teachers in general universities will outline the key points, but some teachers often say "I usually give all the key points", so we can review the final exam in combination with the assignments given by teachers in each chapter, which will often give us a great direction for final review. Our medical major is the usual final exam, and the teacher rarely gives the key points, or one key point is the whole book, so we look for knowledge points in the homework problems given by the teacher at ordinary times, which is really useful.
To sum up, I think college students should have homework. Although our spare time will be occupied a little, it will benefit us a lot, so if we have homework, we college students should finish it carefully. I hope my answer is helpful to you.
