Is money an issue?
Cause even though RCM is said to be a good school, I'm not sure if it's worth its out-of-this-world expensive study fee.
So have a look at the main teachers boigraphy. See if anyone interest you more than others. As in, if someone studied with, say, Neuhaus, he might be more interesting than a teacher who studied with someone who wasn't as great. Also see if they "produced" a few good students, and then listen to those students.
And also make sure the teachers are into the same repertoire as you.
