I dont know about the postgrad programme. However RAM is considered the
Senior Conservatoire in the UK and has exceptionally talented graduates, even the Junior (pre-college) department has some amazing young people. I think you use the word prodigy. (However I could be biased as my daughter attends this conservatoire)
It is difficult to put the standard of performance into words. You are overseas thus unable to attend the many free concerts at the Academy. I can only asure you that I have yet to attend any student concerts at RAM, RCM, Guildhall or Trinity that have not left me feeling astounded at the level of interpretation alongside extraordinary technical skills. On one particular occasion a performance left me in tears it was so beautifully interpreted. I wanted to put the young player in my pocket and take her home with me to play the piece again for me and me alone.
You say that most of the required pieces you played as an undergrad, I am being a Devils Advocate here, my G8, 17 year old daughter can also play these pieces, that doesnt mean she is able to play them to the level of a post grad performance. It is how you interprete and perform at the audition.
Remember the Conservatoire is auditioning you
Not the other way around. You are Invited to audition. It is not automatic that every applicant auditions. So its all,
for want of a better word, elitist. In addition one Conservatoire can turn you down flat and another can accept you. Your audition is what counts. You have to be good enough for them to accept you. It is a mistake to think it otherwise (in my opinion). Your preparation is essential. If you can take your own accompanist that you have rehearsed with for awhile so much the better. Prepare prepare, prepare. Dont be arrogant and think you have done it all, if thats the case then just what are you applying there for?
You can also contact the Conservatoire directly. You will find that most applicants try to have a consultation lesson with a relevant conservatiore professor, prior to application. If you can do that then it will probably help with your queries on standards required.
Re: mcm comments on fees and overseas students, please take that with a pinch of salt. No conservatoire wants their standards to fall and thus loose their rankings! They do not take overseas students just for the money. It is a myth that persists in all academic institutions.
