How would it fulfil all your educational dreams?
The courses would be arranged beginning with the basics and move through the more advanced areas in a gradual, rational fashion. If any applicant can demonstrate mastery of each of the subjects offered, full credit should be given upon payment of a special fee for the test.

What would the courses be like?
I see these courses offered more as seminars or round-tables where discussion is encouraged. I see most of the courses taking place in the environments of each subject, rather than strictly on a campus. Opera and Musical Theatre courses would take place mostly in their respective houses. Speech therapy would be taught in a speech therapy environment like a speech and hearing centre when ever practical and possible.

What would the faculty be like?
Ideally, the faculty would be facilitators, counsellors, and knowledgeable people capable of answering the students questions or finding an answer to their questions. They would be people who continue to prove their efficacy as teachers and who get results that fulfil their students' expectations.

How would you get credit?
By showing that you can do and understand. There wouldn't necessarily need to be grades and tests, but there would need to be a requirement to demonstrate competency, by an appropriate means.
