Students have aspirations, therefore 1-3 star students (from what I’ve seen) only have two classes to take on test. 결과적으로, they only studied Humanities and Sciences at Peninsular, Northshore, and Archimedesbug. If you add Sports or Arts Course(에스) to their schedule, they will gain community points and learn about it in their details, but it will be ineffective for them. The same may be said with Dancing Waffle and BEYOND Civil.
It’s fine to start early if you don’t have enough courses (you haven’t researched Intermediate Courses yet) to fill the program. 하지만, I do not recommend it for the mid-late game. Because you can truly have your students learn upper-grade courses if you have Teachers with high competency, thus your students obtain 100 full marks for entire academic years when they are still in Grade 2.
비록 그렇다 하더라도, I normally offer special courses like Eye-Exercise, Community Serving, Ethics, and so on just to complete the calendar, but you may also assign more advanced courses (예를 들어, Northshore with 1-Star just needs Rudimentary Courses to graduate) to obtain more Community Points. 하지만, even though they are qualified, they will not enroll in Archimedesbug, thus the tuition fee will remain the same.
