HUB isn't bad university, but neither it is an excellent one. I think the University of the Aegean is probably a better one, but it's in Greece, and I think it's very good to get out of there. Personally, I would choose the HUB, and epsecially if I was Greek because the international experience will be great.

Take a look at http://www.bachelorsportal.eu/ to find some other options -- it will be better to have more choices. If your budget is limited, then look at Rotterdam School of Management and the other universities in The Netherlands, especially Amsterdam and Nijmegen.

I am from Moldova but I live in Greece.
In Netherlands, due to my nationality, (at almost all unis)I have to pay from 6000 to 10000 euros and It's too late to apply for this academic year.

I'm not looking for alternatives. I just want to be sure about which is the best option. The tuition fee at HUB is approx. 600 Euros ( nothing compared to the amounts UK's unis charge for instance).

So, as I understand, HUB is a "real" university (in respect of their legal status), but not a prestigious one. (!?!?)

Upon graduation, will I be able to apply for master's degrees at universities like LSE of K.U.Leuven or London Schjool of Business or some other more respected institution of tertiary education?

Oh, in that case you should certainly attend the HUB. It's a real university, and degrees there will be accepted for masters studies. There's a special link between the HUB and the KU Leuven, which mentors the HUB through a formal association.

I share the same opinion.
I have already applied for a Visa, but I always have second thoughts. I am really worried about what this degree offers me when it comes to finding a job.

However, by being admitted for a MBA program at a more prestigious uni, I may be able to "fill the gap', wouldn't I?

After all the degree is not the only thing that matters..

I speak fluent Greek and Romanian, my English is quite good (CPE level) and if I attend classes at HUB I will be able to enhance my English while learning French and Dutch (for 3 years ).
Total: 5 languages

What do you think?

Yes, of course to get into a prestigious MBA you will need three or your years' work experience. With five languages and enthusiasm, I am sure you will find work in Belgium.

How easy is it for somebody whose English is at proficiency level to cope with every-day life's and academic related situations?
Most unis accept a CPE or a IELTS as an adequate qualification. But is this the minimum knowledge of English somebody should have or the level that ensures the fact that somebody could cope with his academic obligations?

Generally, how easy do you think that it is for someone to "adapt" ?

I don't think that the ability to adapt is primarily a question of language skills. Obviously that level of English is the right one, otherwise they'd have lots of failing students and the college administration would stop them. It really depends on you, how far you place yourself in challenging situations, and what the languages and accents are in the areas where you are.

I once read (on Wikipedia) that the Belgian universities have a very simple admission system meaning that students are easily admitted regardless of their grades, which results to high dropouts (due to difficulties they experience when studying).

Of course this involves things like maths skills etc.

Do you happen to know anything about this?

Yes, that's true in Belgium, France, Germany and most of the countries based on the Napoleonic code. In these countries anyone with a good high school result is assured of a seat in a university. The first semester can be very testing for people who are not at university-standard, or who don't really have a strong motivation. The big variables are the resourcing of the university and the motivation of the students. The HUB has Flemish government funding, which is more generous since it's a rich region. While it's true that Belgium has a high very entry rate, it does also have quite a high graduation rate. Look at chart 3.2 here: http://www.ond.vlaanderen.be/hogeronderwijs/bologna/conference/documents/BENELUX_HE.pdf to see how the participation rate falls [for example between 19 and 20] in the traditional universities, in pink. That represents drop-outs. It's pretty modest in Flanders, and I don't think you should be concerned about that.
