Hello S_L,
I am indeed considering the Oxbridge organ scholar route! This is the list I've arrived at after eliminating 3 or so from this year's vacancies.
In an ideal world where I possess organ-playing superpowers, I would've applied to (dare I say) King's or Gonville & Caius. However, in reality, I am neither naturally talented at the organ, nor do I have the necessary experience on the organ (I won't be taking a gap year at a cathedral or anything along those lines), so I decided to choose the colleges with a fairly light workload.
I am hoping to read History or History & Modern Languages. 🙂
