The Mobis Institute, or rather, all the academies of the Academic City used this same elective course system.
Every student would decide the subjects they wanted to take, then report to the class service office to sign up in the morning, where they would receive corresponding key cards that allowed them to enter their selective classrooms.
The institute itself didn't care about which elective you chose, or even whether or not you actually studied.
After five years in the institute, if you still didn't have a certificate issued by a professor of the institute, the institute would refuse to recognize that you had graduated. They would only hand out a bronze academy medal that was equivalent to a certificate of participation, essentially, it would only prove that you had once studied in the institute.
