In exactly the same boat. I currently have BBB. My offer is AAB. Luckily, I pushed to finish everything in 1.5 years instead of 2 so I had this one last exam slot to retake. Just retook bio 4 (unfortunately I was one UMS off last go around.) And then I have math C34 coming up on tuesday which I'm really not prepared for.
I hope we both get the grades we need and if we don't, that Sheffield is nice enough to take us anyway.
