Maybe I'm not the best one to comment since I haven't had any trouble with UCAS (although my UCAStrack number is still in the mail), but I did have a lot of application questions (since I had no idea what UCAS and the UK application process was about) and I never waited on the line more than 10 minutes to get a representative. Then again, I always called at around 6AM my time, which is 11AM or noon in the UK so all of you would have been in school and presumably not calling UCAS.
Anyway, applying to schools in the US is a pain in the ass, and I tell friends about how I applied to 3 schools in the UK (and making it 6 would have taken an extra 15 seconds) in half the time it takes me to complete a single US application.
For the US, you have to enter all your personal data seperately for each school. And it takes longer because besides the basic "name, phone number, address, birthday", they ask whether you visited the school, when you visited, whether you know anyone who is an alum, what year they graduated, what academic distinctions you have earned, what extracurricular activities you took part in, any jobs or hobbies you have during the school year, any internships or programs you went to over the summers, etc. Then, instead of a single personal statement for all schools, which makes a lot of sense for a variety of reasons (besides that its really easy, it means that people won't be able to ******** as much about why they want to go to a particular school), I just finished an application for Northwestern University where I had to write a 500 word essay, a 300 word essay, and four ~50 word short answer questions. And they're not all really pertinent... most are basically creative writing assignments.
And then remember that thats all for one school. Application fees are usually $40 to $65 per school, which is more than a single what you apply to up for 6 at UCAS.
But then I suppose the American system has some advantages. Schools themselves get to choose what they're looking for, plus if you have a parent who went to the school you get a few points. Plus you can apply to as many schools as you want under our system, and if you want to apply to every single Ivy League school, that's your perogative (you're paying for it in application fees anyway). To an American, it's extremely strange that you guys aren't allowed to apply to both Oxford and Cambridge. Also, 6 schools is about the minimum that most people apply to- 7 to 9 or so would be the norm.
I really like UCAS though... I was able to apply to LSE, UCL, and Warwick, in less time than it took to apply to any single American university.
