What are some intermediate ballet R.A.D routines?

If you are wanting to learn dance at RAD Intermediate level, then you should not be asking this question here. There's no such thing as an Intermediate 'routine', only the set exercises from the syllabus. You need to find an RAD registered teacher who will actually teach you how to do all the exercises properly, and who will train you in the correct technique. Intermediate is one of the vocational graded exams, and the technique and terminology are far too complex to explain in one short message here, it takes most candidates at least a year of training to prepare for the Intermediate examination, doing 3 or more lessons of ballet a week. If you want to learn this work, find an RAD teacher and take lessons like everyone else, ballet is not something that can be successfully self taught.
