I certainly dont consider art to be an easy BA or anything of the kind, and Ruskin hs a fine reputation to be sure, but I'm always wary of art students who want to study there because its important not to confuse the reputation of Oxford University and the Ruskin: in the art world, it will matter that you went to the best place for art (i.e St martins, Chelsea, etc) as opposed to a place which has a great academic reputation. Again, I'm not saying dont apply, or that its a bad place, but be aware the London institutions are generally more respected for art for a whole host of reasons.
