One the things that most surprised me in this MBA is the excellent team spirit. It's great in this intensive year to have most or all your colleagues willing to help you in some kind of problem that you have... I'm not saying not only in academic issues, like in some subjects, but in regular stuff, like giving clues, tips and contacts about internships, future prospects, feedback, everything! It's a give an take relationship that everybody takes advantage of it.
I had some doubts about the size of the class of the Lisbon MBA program (we are only 30) but now, to me, it makes all the difference: I know all my colleagues and everybody knows me, but also the goals the strengths the weaknesses, which it makes the difference in this demanding year. In my opinion the size of this class is perfect, even the professors (at least most of them) are really attached to us and treat us all by our name and are really interested in ear what you have to contribute.
Team spirit of the Lisbon MBA - one of the greatest assets of this program.
