University elective courses can be roughly divided into two categories: public elective courses and professional elective courses. Public elective courses generally require low credits, about 10 credits, and some schools have restrictions on humanities and science and technology courses that contain several credits. Professional elective courses are generally only provided to students of this major, and most of them are professional courses, with a total credit requirement of more than 20 points, which is an important way to master professional knowledge. The credit requirements of elective courses are generally hard indicators for graduation, and only after completing credits can you qualify for graduation. Tuition in some schools is related to the academic performance of elective courses.

* * * University elective knowledge: students must be given full choice. This right of choice is not only the due right of students as education demanders, tuition payers, individualists and school management participants (democratic rights), but also the due right of professors as education providers, academic decision makers, individualists and school management participants (democratic rights).

Course selection time: general undergraduate schools start from the second grade. Generally, it is conducted on the educational administration website of the school, and the next semester is chosen in this semester.
