My DC did the triple BTEC in Performing Arts plus one A level (Drama). It was her dream. I was very worried. (I'm a conventional academic.)
She auditioned for acting schools and was offered an unconditional place at East 15 Acting School which she accepted. It's part of the University of Essex for degree accreditation purposes. She graduated with a First in her particular specialism. Her graduation ceremony, presided over by the University Chancellor John Bercow, was unforgettable (as opposed to my dreary graduations) for all the right reasons.
My DC shone with happiness.
She now lives in London and I'm not going to lie to you, she struggles financially. But she's performing in between shifts at The Day Job That Pays The Rent, she has great friends, and is writing and creating as well as being on stage.
I'm very proud of her and I'm glad I didn't push her into a History or English degree that I suspect she'd have hated. The degree she did broadened her mind, developed her talents in acting, music (voice and instruments), dance, writing and staging, and taught her huge amounts about literary canons (from Sappho onwards) and acting theory, as well as practical applications of this knowledge for the industry.
I would just add: auditioning was tough, competitive, and expensive (travel and fees). But when she got that letter from East 15 ... wow. Her face. And she loved it.
