When you're a full degree student, you get three chances to pass. You just have to register for reexams when you have failed.
In France, when you fail, you have to wait the end of the year, or even September, to get a chance to pass. In Aarhus, there isn't any Second Session (as we call that in France.) You do your exam during the following semester.

About semesters...

In France (yeah, I'm French, and French Uni are my only reference!), when you enroll at Uni, it's for a year. You can't begin your education by Spring semester, for example. (At least in most Uni, I don't know if every uni in France work the same way, depending on the subject or area.).

In Aarhus, you can't really speak of academic year. Of course, there is. But the most important is the semester. In France, you get a confirmation of enrollment once a year, when you enroll. In Aarhus, you get to print your confirmation in each semester.

You can apply for a full degree study which begin in September or February. You can apply for a PhD scholarship that starts in August or January.

Let's say it takes you 5 semesters to complete a Master (usually 4 semesters, but we never know!), then you are a student for 5 semester. While in France, 5 semesters equals 3 years.
When you're finished with your studies, you have to quit university officially, by filling out a form. Isn't that amazing?

You can chose the courses you want, that fit in your study program. In France, it's quite rigid, structured, and you have to follow mendatory subjects. You get more freedom in what you want to study in Aarhus.

The exams form are quite different. Usually, at a BA level, you get written and oral exams, maybe some paper to write, and your BA project, which is a kind of mini-thesis.
At a MA level, most of your exams are essays, with or without oral exam (in the case of an oral exam, the essay is only a synopsis.) The last the semester is focused on the master thesis, there is no courses.
That makes quite a difference between France and Denmark. I've been three universities in France (Paris, Clermont, Caen), and most of examinations are written and oral exams. There isn't any BA project. So to speak, when we arrive in MA level, we have almost NEVER written any paper, and we're told "well, you get to write a thesis, ca 100 pages." That is a bit scary, when you think of it!

Well that was it for today, just consideration between two different systems...

If you miss your Dr Pepper, you can find it in SuperBest (a supermarket) in Vesterbro torv. A bit expensive (what isn't in Denmark anyway?), but yet, here it is.
I really love this drink. Sweeter than Cola, with a taste that reminds almond and a bit of cherry.

That may be one of the hardest things!
There's a lot of students. There's not so many rooms.

If you're an exchange student, the International Secretariat can find you a room.
If you're a full degree student, you have to help yourself.

Fortunately, there's some solutions. But unfortunately, you have to be patient.

I recommend you go there: http://www.studenthousingaarhus.com/ and start your application around six months before the beginning of your studies in DK.
As you can apply six month before you start your education, I really encourage you to do so. You enter a waiting list. You can be on the waiting list for months before you get an offer and hopefully a room. You don't want to wait for thee months when you arrive in town, do you?

The principle is easy: you select the accommodations. When your application is done, you come on the waiting list. You have to be active, this means you have to "reapply" (by suppressing or adding few choices in your list) every month. It doesn't matter when in the month, as far as you do it every month.

There is a case "applying for housing guarantee", tick this. When an offer comes, maybe it's for you. That's a new policy to provide accommodation to all students.

You can refuse 2 offers. The third time you say no, your application is cancelled and you have to do it all over again.
When you say yes but don't get it (depends on your position on the waiting list), you usually get the next offer.

In Denmark, as far as you can pay the rent and the deposit, it doesn't matter where you're from and if your family is rich or not. They usually don't ask for any guarantee. The only thing is you have to pay the deposit and the first month rent  winthin the first days (sometimes the first two weeks). That may be hard. A deposit can go up to three or six months rent (in private accommodation). Fortunately, in students residences, the deposit goes from 3000 to 9000kr, depending on the room size, the location and so on. The average, I may say, is 4000 or 5000kr for a deposit. You usually get it back when you leave.

You can also try some professional sites, like AarhusBolig and the like. There is a fee (150 to 500,- depending on the company), and you have access to announces and offers.

I don't know what else I can say about accommodation for students.... I'll try to figure it out later...
