Given how competitive med is, I'm amazed they promoted it as a route into that course. You're likely to get multiple rejections even coming from AL/IB.
They don't have any control over who accepts it externally, although I'm glad the AAB candidate was reassessed.
FY's are by-and-large, a a rubbish option for most candidates and close more doors than they open. We've been advising people this on TSR for years but if UCL have been miss-selling then it should be reported to the OfS.
