Not really.They sent me a similar email this morning. While I appreciate the very low threshold in SJT it seems very pointless, don't you think? The amount of people under 495 will be like 5% of the cohort. The people who did reallyyy well in the UCAT have no reward, and I'm saying this as someone who didn't have particularly high UCAT results.
The low threshold reflects the fact that they are using UCAT, an aptitude test, to eliminate those particularly lacking in one of the aptitude areas tested by it. I can't remember where I heard it but I believe the more recent thought is that grades are a better predictor for performance in med school anyway. (I won't even try to address the nebulous "good doctor" concept, which goes well beyond just grades or aptitude - and the uni's core business is really to take your money and the government's money and get you through the course.)
In real life, being really good at something often carries no reward, compared to being adequate.
