Any question answered...

So if you don't get your predicted grades you can do an interview or whatever to try and get in?

Way it works in Ireland is that you sit your equivalent of the A levels and there's grades like A1 90-100%, A2 85-90%, B1 80-85%, B2 75-80%, B3 70-75% and so on until you get to D3 which is 40%. Each grade is given a points system, A1 is 100 points and a D3 is 40 and so on, and you add up the points of your top 6 subjects. You can only get a place in the course you want if you get more points than the lowest person who was accepted.

This means it's totally fucked if loads of people apply for a course. For example, Computer Science has gone up by 150 points in the last 3 years.
I get my results on Wednesday and I'm absolutely shitting it and looking in to going to London to study in case.

It's fine, you can always do the course at a shit uni.

uni and its a joke anyway. The 3rd year is the only one that really matters and it lasts about 6 months. most of the dudes on the course just got other people to do their work anyway. You'd be better off teaching yourself what you want to know and picking up your own jobs along the way to add to your resume.

But of course you'd be missing out on the fun of uni, which can be had on a lot of courses even if its not your chosen one. Go for a course you;d like to learn about that will have the most likelyhood of chick in, same with choosing societys to join. If I knew back then what I know now.
