Sure, I know it can be a big step coming over here to study! I've personally not stayed in dorms, I've not heard good things and a lot of people who start off there usually end up moving out. I stay privately in a flat not far from the uni that I got through a student agency. There's two agency's that can help you get a flat, one is called foreigners and the other forstudents. I've been with both, and I personally prefer foreigners, many students have complained about forstudents but I won't go into that right now.
About the course and studying, yes it's tough, especially the first two years as you're trying to get used to the system etc. You'll have a lot of tests throughout the semester, then a credit at the end before sitting a final exam. But the good thing here is that students help each other out. There's lots of notes, past papers etc and advice from upper years to help you get through the years.
Hope that helps a little, feel free to ask any more questions.
