You can get into a number of RGs for law with AAC -- Liverpool, Cardiff, Southampton, Sheffield. But improve your grades, and you could get into even better ones.
Despite what teachers and others say, RG is not the holy grail and you can do perfectly well studying a degree at a uni outside it as long as the non-RG is as good as most RGs. Surrey, Leicester, Lancaster -- all are at least as good as Liverpool or QUB.
RG is just a convenient proxy for quality; but as long as your uni has that quality, you're laughing. Similar with Ivies in the US; you go to an Ivy so you're quite bright, but you're no bright because you went to NYU or Stanford or MIT.
