Merton! I <3 Merton. And believe me, we're not (all) academic high-fliers! I bombed on my collections - 55% - with the best scoring 96%. Ah well... Regardless, our rent is very good (the best, by the looks of it), with accommodation provided for all 3/4 years of your course - the best rooms in college are absolutely amazing, and we have a really fair ballot and pricing system - set price for bedsits and set price for sets - rooms are random for first years (who all live together-ish), then ballot for 2nd year, reversed ballots for 3rd year, and re-balloted for 4th year scientists/mathmos (there are funny but sensible for linguists and classicists). Food is at best - really really tasty! - at worst - relatively tasteless, but still completely edible. Merton lunch is amazing for £2.something - if you get there early, you can get soup, main, salad, cheese and 3 desserts! And it's so pretty, especially what I've seen of Merton in Spring and Summer! And everyone (and by everyone I mean everyone) is really very very friendly. And I almost feel glad that my tutors are going to ensure I get a good grade, whilst not actually having felt much pressure at all from them yet!
Basically, Merton is amazing. Apply! Apply! Apply!
