Good sixth forms/sixth form colleges for classics?

I am a Year 10 student, and when considering what I want to study further in the future, I have really developed a love for Classics. I plan to study Latin, Greek, Classical Civilisation and maybe Music/Music Tech at A-Level, so I would like to know if there are any good sixth form colleges with good classics programs? Or just some that are generally highly regarded? Ideally in the Harrow area.
