advice on uni options

so i took a gap year initially i got A*BB in pysch bio chem. I retook bio and chem i dont think i got higher than last year. I reapplied to medicine and i got an interview for King's but then i was waitlisted - there are 20 people on the waitlist. I got an offer for Neuroscience at King's but you need an A in bio and chem for that, which I know is impossible for chemistry after those exams. My insurance is an unconditional offer at Qmary to study neuroscience. I asked King's if I don't get the grades for Neuroscience but I get the grades for the medicine course which is only one A in bio or chem (EMDP) would i still be considered for a place on the waitlist and they said no as we are not allowed to poach you from another university. I want to move out as well as I want to get away from my strict dad who is limiting my potential. After the neuroscience/biomed degree I want to do Medicine. Both Qmary and St georges allow you to transfer to Medicine, either after completing the degree or after 2nd year.

my qs are:
1) I've heard lots of negative things about Qmary the students and the area, is it a bad idea to move out there or should I release myself for clearing and go to St George's for biomed and live out there?
2) Is it a good idea to remove my insurance so that if I don't get my grades for Neuroscience but I do for the EMDP programme I can still be considered, and then if there is no place at all I can just study biomed at St george's?
3) I think I will like Neuroscience more but which uni is better overall St George's for biomed or Qmary for Neuroscience?
