If you can afford it, a set in Mem. court is THE best accomodation you'll ever get. EVER. Unless you get the room on F staircase above the Thirkill room (in Old Court) which looks out over Kings and the backs. Or the room on either B or C staircase that's over the entrance to Old COurt and has original C17th Oriel windows. But these tempting delights await you in third year. Not me, my ballot number's not high enough...
Seriously, if you can take a good passport photo, do so. Mine was taken way back in 2003/4, and is now on my university card. It looks not a great deal like me. I'm green. It's strange!
