It doesn't matter if you hand in your homework, it won't affect your credit. It's just that the final exam has something to do with the exam results in the university, which is the exam results plus the teacher's recognition score for your usual performance! For example, you scored 50 points in a scientific research, but you usually hand in your homework on time in class and do well. The teacher gives you 15 points, so your final score is 65 points, passing! I got the honor! Therefore, whether you hand in your homework at ordinary times is related to your grades! If you can ensure that you pass the exam, you will be fine if you don't hand in your homework once!
