Attend Your Classes Regularly
Nowadays it is a very common phenomenon that some university students are late for or even absent from classes. And still there are some students who slip out of the classroom before the class is over. Class attendance has become a thorny problem to both the students and teachers.
In fact, it is very important for the students to attend their classes regularly. First, it will ensure you to catch up with the teachers in your learning. That is very helpful to you if you want to do a good job in your study. Second, attending classes regularly is a way of showing respect to your teachers ,too. Your teachers will feel bad if the students do not attend their classes, which, in turn, will affect their teaching and be no good for the students. Third, attending classes regularly will help to form a good habit of punctuality, which is of great importance for the students to do a good job in the future.
Therefore, we university students should form the good habit of attending our classes regularly from now on. And some day we‘ll benefit from it.
