Thanks, but what if I couldn't get into either of my 5 choices? Like I'm sure a lot of UK students would want to start with a large variety of choices to begin with then reducing it to just a few. If one can only have a maximum of only 5 choices, then doesn't that mean quite a number of undergraduates out there are unable to enter any higher education school at all?
Usually, the majority of UK students are applying to university before they have done their A level exams (ie finished high school). They are advised to look at their predicted grades and apply for courses accordingly- so they are within their reach. These students may then be given a conditional offer, depending on them getting their grades in their exams in the summer. If they fail to get the grades, and the university won't take them, or if they don't get offered any places, or even decide to go to uni at last minute, they can use a system called the clearing system. In the weeks before term, universities advertise for places on the courses that have not been filled.
As I mentioned before- I don't know if it is possible for overseas students to get a place through the clearing system- there may be funding issues, and it only opens the august before term starts.
