lol, without living costs and books university costs around 550€ here a year. If you calculate 800€ in total a year you're fine here. 800*5 years makes 4500€.
€800 a year TOTAL?? thats crazy cheap...but i suspect you do the typical european thing of going to your local University and living at home? that's not typically practised here in the UK. We generally move away from home so that's why it is more expensive.
