University teachers are not as strict as junior high school teachers and do not require every student to understand. He will continue to speak according to his own process. For the part that students don't understand, they can ask the teacher for help after class, but they will follow their own rhythm mode in the course. So university teachers simply don't have much time to take care of students' own problems. He hopes that students can understand the importance of learning and finish their homework consciously.
Second, although university teachers will also call the roll to sign in, most of the time they will not call the roll, but draw lots, which gives some people a chance to be glib.
When I was in college, in fact, most of the time I would call the roll, but he would only check a few people to call the roll, and sometimes he would call the roll on their behalf. University teachers are not stupid, and he knows all kinds of behaviors of students, but they are only university teachers, not class teachers, so they may write down these behaviors of students and deduct a certain score at the end of the year. But as long as the number of skipping classes during college is not too serious, teachers are basically not particularly harsh.
Third, in universities, students need to accumulate more credits if they want to get a diploma. As long as you pass the exam, you can basically get credits, so you just need to work hard before the exam, and you don't care much about the courses of university teachers at ordinary times.
Many people think that college is a time to play, but it is not, which will give many young people a misleading behavior. In fact, universities need to study hard to get their diplomas. Although it is a credit system, if you don't study hard, you won't get this credit. It's not that college teachers don't care much about every student. They only care about their own courses.
