Students must complete the minimum required grades of compulsory courses and elective courses stipulated in the professional teaching plan during their school days, and this must be the case every semester. If they don't reach this point, they will be warned of their achievements. You can't graduate until the credits have accumulated to the professional requirements. If you haven't finished it by the time you reach the senior year, you may be asked to stay in school for one year and finish that part of the credits before graduating.
