Yay for county council grants paying all my college fees, then. I didn't even need to take out a single loan during my time in college.
Over here, your six highest grades from the leaving cert are converted into "points", up to a maximum of 600 (100 points for between 90-100% at higher level, 90 for 85-90%, 85 for 80-84%, and so on down to 40%, below which you fail). Early in your final year, you choose a bunch of courses from different colleges, and order them in preference. The one highest on the list that you get enough points for is the course that's offered to you (all lower ones are not offered, regardless of whether you actually qualify for them, so lots of people actually miss out on courses they want, by ranking them too low in preference).
It's actually a really bad system in practice, as it puts too much emphasis on your ability to cram for the final exams. They've been talking about changing it for years, but of course nothing much ever happens.
