You can graduate with a diploma, but you are not satisfied with your credits and can't get a degree certificate. Credits can be used to judge the breadth of knowledge learned by students during their college years. The more credits students get, the more things they learn. In some universities, credits have also become an important criterion for evaluating students' Excellence.

The total number and structure of credits obtained meet the graduation requirements and are the main basis for students to obtain graduation certificates. Therefore, the main purpose of implementing the credit system is to provide flexible curriculum management programs, not to evaluate students' learning quality.

The general calculation method of minimum credits per semester is:

Minimum credits per semester = total credits /2× (standard academic system +2)

At the same time, the credits of each semester shall generally not exceed the maximum credits stipulated in the professional teaching plan. If there is over-election after examination and approval, the over-election fee will be charged according to relevant regulations. The general calculation method of the highest credit per semester is:

Maximum credit per semester = total credit /2× (standard academic system-1)
