I just asked my deputy head. He comes from Zheng Da University. It depends on the regulations of your school. You can't graduate until you have completed all the credits. In addition, you can apply for a second degree examination. If your school stipulates that you can get a bachelor's degree if you fail less than 25 points, then your method is ok, but there is one thing. It is a compulsory course that must be passed. Failure in compulsory courses can't be compensated by credits in elective courses.

You can only apply for the senior year. I'm afraid credits can't be bought with money. Generally speaking, if you apply for repeat study, you will get one credit in 200 yuan, just like our school.

If they all pass, it will not affect the diploma and degree certificate. If there is no delay, they will be sent together.
