Original post by flutefluteThe St John's room grading system makes very little sense... we actually have two separate grading systems, and have rather a lot of grades: D, C-, C, C+, B-, B, A-, A, A+, A++ with very little definite reasoning for why any given room counts as being a particular grade.
There are some A- rooms that don't have an ensuite. The room I'm typing from now is an A and has a toilet/sink ensuite, but no shower. I imagine pretty much all A grade rooms would have a separate bedroom, as well as the main room (or otherwise just be really really massive). The big rooms are probably a bit less lonely when you've moved your stuff in!
