2700 B3 UCAT - Unis?

I sat my UCAT yesterday and I wasn't too happy with my score as I was scoring higher in mocks. But it is what it is. I was thinking of applying to St George's, Queen Mary's (very aspirational i know), ARU and some others. Is it worth applying to St George's with my Band 3 SJT?? And also is it worth applying to Queen Mary's? I'm really conflicted on which unis I should decide and I really want to study medicine in London. Please help!!!
