I am hoping someone can explain to me what I seem to be missing. Attached are the syllabus for the Blackpool Teacher/Student events and the Pro/am events. If I read right, in Teacher/student any student can dance with their instructor whether that instructor is a pro teacher or an am teacher. Either type of instructor must be registered. In pro/am, the teacher must be a registered pro. On teacher/student it states that teacher/student couples cannot compete together in any other events. So if you dance with a pro teacher, you can do either teacher/student or pro/am, but not both? Since the cost of pro/am entries are twice the cost of teacher student (199 pounds vs 100 pounds), would anyone choose to do pro/am? Is there a distinction I am missing?
