what do you mean, the courses with social political education? It was always there. From my education experience in the late 80s to 00s. But to be honest no one is ever taking it seriously and it's obviously a joke to students.
No, no. Single politics course, they do exists, but never single Maoism course, single Dengism course, etc. Even in colleges and universities they're combined into one single course. This time it's different, China is having single Xi-ism course.
