Write a list of things you wanted from the university itself beforehand, e.g. location, the things that the course offers and then when taking another offer from university it gives you the chance to find out what that university offers so you aren't too disappointed when you arrive at your university.
Stay postive, it's super important to remember you've still done well enough to get into university, and although it may not have been your first or second choice, there are still options. Which means there are still paths you can take to achieve your dreams.
See what is out there, talk to people like universities, colleges and careers advisers as they may be able to help you find a new course or help you by finding another alternative to what you want to do, remember university isn't the only option.
For those of you who are coming to the end of your courses, I think this video will be super helpful for ways to better yourself and learn about life outside of university.
