What things are you worried about? I originally applied to Aberdeen and edinburgh for geophysics this year but ended up changing my mind about what I want to study and choosing my insurance which was environmental science in Aberdeen. Most of your recent posts are you being worried about Aberdeen's rankings. Is it just BC you are Edinburgh reject or do you just highly believe in rankings? You even mention that Aberdeen's rankings are not good at all which is honestly a bit of a reach.
Obviously I'm biased as it's my future uni and I want to think highly of them but I'm expecting to have a great time. If you are obsessed with rankings then you should remember that in overall rankings it's top 30 UK and top 20 in physics. Also you can always mention that it's one of the ancient ones even if it doesn't rank as high as others. After all you are going for your undergrad. In a lot of STEM fields like physics that's only one of the steps in your career.
