Right, for most Arts subjects the Oxford colleges seperate themselves into 3 different groups, so that your second and third preference colleges will alwauys come from the same group as your first preference college.
Group 1: Brasenose, Christ Church, Jesus, Lincoln, Magdalen, Mansfield, Merton, Oriel, St Hilda's and Somerville.
Group 2: Balliol, Exeter, Keble, Pembroke, St Anne's, St Edmund Hall, St John's, St Peter's and Wadham.
Group 3: Corpus Christi, Harris Manchester, Hertford, Lady Margaret Hall, New College, queen's, St Catherine's, St Hugh's, Trinity, University and Worcester.
Is it just me, or does Group 1 look like it'd be incredibly difficult to get into for Law? Or maybe all subjects? I don't know a great deal about the different colleges prestige and difficulty to get in, but it does seem that Group 1 is packed with a disproportionate amount of the best colleges.
