Hey,
1. As regard to scholarships, I think they are rarely granted to incoming Bachelor students. Most of them (if not all of them) are offered to Masters students, I have a friend who got one.
2. The University provides accommodation for students through maastrichthousing.com. You can also check out
http://www.unimaas.nl/guesthouseum/. For other accommodation plans, just ask me if you have more questions, they are lots of landlords that offer accommodation ranging from 250-350€/month. The landlords usually advertise their rooms through Facebook groups or agencies in Maastricht. If you cannot go to Maastricht for flat hunting, I would advise you to stay a couple of months in the University-managed accommodation, and then take over a flat. However, I would like to warn you: I've heard some not-so-glamorous stories about the GuestHouse UM, it's quite the party place to go, the kitchen becomes quickly as dirty as a football pitch after a heavy rain in a matter of days, so.. Better pass your way! The best if I were you would be to go to a Facebook group and contact people, and stay in a short-term accommodation by that time.
3. I have never been to the UK for studying so I cannot really tell you. However, the teaching in Maastricht is rather practical-oriented if I could sum it up in one word.
As regard to the number of teaching hours, you have class roughly 4 to 6 hours a week (yes, you read it right), where you have to solve cases. It's interesting as it looks like you are handling real-life situations! You have several presentations, papers to hand in etc. The year is divided in 5 or 6 blocks of 7 weeks. You usually have 2 courses per blocks worth a certain amount of credits (usually 6 or 12, or 16 at maximum), after the 7 weeks, you have one week of exams. It is really nice as it helps you to focus on certain topics, then you have exam and you take new courses! So you don't have to drag a course you don't really like for like one semester!
However, the few amounts of hours you have in class suggests that you have a lot to do and prepare for the for the class. You have significant amount of reading material to read, essays might take long to write, and they are really (at least in Law), looking for precision, well-reasoned answers in your exams. The system might be a complicated for some people, but hard work always pays off. Even if the drop out rate is quite high (in some faculties such as Law), you can always manage to get into the second-year.
3. As regard to your concerns about doing some particular courses without have some extensive knowledge about it, I would say: Don't worry! The coursebooks are really well-explained, the tutors are very approachable, and you will have quite a lot of time for studying so don't worry too much. Once again, I cannot really talk about economics but for Law I did not know anything, my English was quite poor and I could barely speak in front of the class without chewing most of my words! After almost two years, I am now ready to take my first moot court competition, in a foreign language, and with a sound basis of law. If you are motivated and passionate about your studies, there will be no barrier at all for you to make it.
