Assumption: Registering one student for one course is the basic unit of work. So registering one student for ten courses takes the same time as registering ten students for one course each.

300 students x 10 courses for each = 3000 studentCourses 3000 studentCourse / 4 hours = 750 studentCourse/hour For any number of courses and students, just divide by this work rate.
