Well, I agree with you about it not being fair to accept international students with lesser qualifications, but since when have university admissions ever been fair? University admissions are so unpredictable and universities are looking for other factors than mere academic qualifications. They want people who are going to contribute to other areas of the university and who are going to be successful in life, which is not always measured by Scottish highers or SAT scores or A levels. US admissions at top unis are very much a crap shoot; there are people who have perfect SAT scores who are rejected and seemingly less qualified candidates who are admitted because they are more well rounded, wrote better personal statements, ect. Or even because they are hispanic, black, international, ect and the uni wants more diversity. It's not exactly fair, but at the same time, uni is about expanding your horizons, meeting new people from different backgrounds, and becoming more worldly- don't you think you would get bored with a very homogeneous university population? I know I would.
And while univeristy admissions may seem random and arbitrary, there sometimes is a method behind the madness. Some people really do write spectatular personal statements that are much better than than the straight A-genius. Some people really have overcome numerous hardships that make them much stronger people than their fellow counterparts applying. I am very glad that universities are not wholely number based, because (shock, horror) maybe your grades do not measure your entire worth.
While I understand your concerns, know that, as Mishy has said, universities everywhere seek international students and these students may be perceived as hogging up prime spots. But at the same time, I think there is something to be said for the international applicant. Oftentimes these people are more driven and hardworking because they took the time to look outside the bubble where they grew up and know more about what they want from their education. I do not resent any of the international students taking up spots at US universities... most of them deserve to be there.
While St. Andrews has a lot of international students and applicants (hah I'm American) last time I checked the ratio was something like 2:8, so I don't
think the school is going to be ambushed and taken over by the international students anytime soon. I don't think you'll be taken hostage, if that's what you are concerned about. The university does have restrictions on the number of international students they can accept!
On a side note, hey Mishy! I see you have found my new home away from college confidential!
