It's really hard to judge as it is wholly dependant on who applies, and how many people Sheffield decide to interview.
There has been some talk elsewhere of cut offs going down at other unis, but these are normally those that score GCSEs. Sheffield is a straight UCAT one so that logic doesn't apply here.
It's guesswork. But so is it all.
My personal view is that it will go up, because it rarely seems to go down, but no idea how much by. I would probably want to have min 30 on last year and keep my fingers crossed but it's really just a comfort thing.
