I took my LLB at a British university and although I came out with a 2.1 my grades breakdown is less than impressive, especially in the first two years (although within the context of my uni they were actually compatively high - at least they were sufficient to win me a couple of scholarships). I'd now love to do a Tax LLM at one of the US Ivy Leagues but I'm concerned I might be stymied by my undergrad results. I did subsequently go on to work at a well-regarded firm and have professional experience in tax. Would anyone be able to offer a realistic idea of my chances?

Many thanks.
