Hi there,
Congrats on your offer from Glasgow! The simple answer is: no, it does not! Its a shame to hear that you didn't get an offer from Birmingham but this has absolutely no bearing on your chances at any other uni, its just a case of waiting and seeing what happens. Whether you get an offer or not will depend on many factors, and each uni is subtly different in how they look at each factor. Therefore you still have every chance of getting offers from your other unis - just bear with them 🙂
Wishing you the very best of luck with your next steps!
