Gimfl is not like common high school, there are many different systems.
Especially, the number of students is only 126 in a grade, 26 in a class. Isn't it advantage and speciality in GIMFL? We can make sincere friends in our class for 3 years. but I never mean other class students aren't important. I think only 1 year is too short to know each other well. Also, we already tired and stressful to study hard. If we had to change classes each year, we are so stressful to adapt new class, new friends. new environment. As I said before, Gimfl students are only 126, we have enough chances to get along with other class students. And we are doing well now! In short, the class system in Gimfl is good enough.
