Hey guy, just wanted to offer some encouragement to anyone embarking on an Access Course for 12/13. I'm currently midway through one now and although it can be difficult juggling the assignments it is a very doable course.
The best advice I can offer is to aim high. There isn't a single university in the country that won't consider you. I've been offered places from great institutions such as Uni of Manchester, Leeds, Bristol and Loughborough. Even the thicko's on my course have somehow managed to gain places at Kings, Soas, Brunel and Bath so aim high, put together a great personal statement and get them Merits and Distinctions in early as it eases the burden later on.
Any questions feel free to ask (quote me). Best of luck
