from my experience, UCL is tougher than LSE for Law..because they use your LNAT score and essay as part of your application. I got a 17 in my LNAT, and got rejected from UCL, but got accepted by LSE. Durham is actually pretty easy to get in if you hav solid grades...their standard offer is AAA, but they will lower it down to even ABC if your personal statement and academic backgroud is good. LSE and UCL will normally offer AAA regardless, but Kings wud be possible wit your grades. But anyway, you still hav one year to work on getting AAA, which isnt a huge mountain to climb wit your current AS grades..so good luck!
