You don't have to include all 4 AS levels on your application, so personally I would just leave the U out, plus it's not a contributing factor nor does it really relate to the structure of a law course. However, as said above I would apply to some universities with the high grades you are targeted (Kings/Qm/York/Sheffield) RG universities, BUT also apply for some 'safer' options, as I know how stressful A2 can become, and it's nice to think that if you don't achieve everything you originally wanted, you always have something to fall back onto! Also, are you sure you want to study law, have you been to open days and read the module specifications and what the course entails- something I didn't do, and here I am, not sure whether I should have even glanced at law, but then again I am very indecisive! GCSE's aren't a worry, yours are good, plus they aren't really taken into account, as for your AS levels, also very good standard! Uni's with not so high standards are: Liverpool (RG), City university, University of Law, Aston, Kent, but don't limit yourself, your grades are looking great and if you're determined i'm sure you'll smash your exams and make it to a RG uni! If not- there's always clearing!
