Took me about a year to pay off the debts..
20,000+ pounds over a 4 year course, probably closer to 40,000 if you adjust it for inflation. I got a good job, lived with my parents and spent as close to nothing as possible for a year inorder to pay it off rather than drag it out by paying back as little as possible in order to party
We have a slightly different system in Australia. The government covers the cost of our university degree and then we pay back later after we get a job by paying extra tax until the amount is paid off. I had everything paid off by the time I was 30.
If you want to pay up front you can and you do get a discount. Obviously that's only something the rich could consider. The best part about our system in Australia of course is that you don't have to be rich at all to get into university.
