How many Muggle-borns had transferred to MMA this week, varied by year. Because of MMA’s rule that the school would ban a student from in-person school-attendance on their nineteenth birthday, no seventh-year Muggle-borns had transferred to MMA in the past week, ditto sixth-year-Muggle-borns; and only one more fifth-year Muggle-born had transferred to MMA: Justin Finch-Fletchley. On the other hand, all eleven Muggle-born firsties had left Hogwarts, less than a week after their Sortings; and all but one of the Muggle-born second-years had transferred out too.
