At First University, courses were categorized as large or small based on the number of students enrolled. They were also classified as general or specialized depending on the level of expertise required. Additionally, courses were divided into core and elective, determined by their significance.
Zheng Qing's class was Astronomy Class 08-1, hence Magic Language was their specialized core course.
History, which extended from Magic Language, was a specialized elective course, which meant there were minute differences in the book lists of each freshman in Astronomy Class 08-1.
For instance, Philosophy of Magic wasn't a compulsory requirement at Alpha Academy and Starry Sky Academy. It was a general elective course. To conserve teaching resources, the school arranged students from different faculties or classes to take classes together. This kind of class was a large course, with students numbering up to a hundred at times.
