well which uni do you prefer?
Why did you not choose UCL?
I'd put QMUL as your insurance then either way, your in London. Edinburgh is a better option since it is more respected but you haven't mentioned it so im guessing you dont want to go there.
If you want to go to QM more than aberdeen, put QM as your insurance. Never put a uni you arnt 100% sure you want to go to as your insurance. At least your at uni wont keep you happy for 3 years.
I didnt even have an insurance because of this.
Well, QMUL is in Extra for Geography, which might mean that it will also be in Clearing, and therefore there is a chance that they might reduce their offer if you don't get the required grades.
I would say that if you really would be happier there than in Scotland, then take the risk. If it all goes totally pear shaped, there are usually decent enough courses in Clearing as a last resort.
