Congratulations on your admission! I am an AFP concentrator, however, I am on Student Government, and have addressed the African Studies issues. Your perceptions on African Studies are accurate. The course selection is pretty limited. The econ component, in my mind is EXCELLENT. The profs at the BC, in my opinion are, overall, good.
You are doing the right thing by investigating SAIS BC before choosing. I urge you not to rely solely or even substantially on the SAIS BC brochures. The BC campus is VERY different from the DC campus. A few people have asked me some specific questions on this website and I responded in a pretty detailed manner. Here is what I have written...
=========
I am not a Latin American Studies concentrator, but from what I gather from those who are, the program at the BC is good. The course selection is decent and the career services for LA studies specifically may be the best of all the concentrations (I believe they more actively help you find summer internships, and in addition, have organized trips to LA countries. For instance, this year a few students from the Bologna Center went to Costa Rica on a school trip?). If items like guest speakers are important to you, very few, if any talk about Latin America. Again this may be natural since in fact you are on a European campus. In addition, there is quite a large contigent of LA studies concentrators at SAIS BC. So that is a positive as well.
American Foreign Policy on the other hand is a totally different issue. Only about a handful of students. There are courses offered, but they are VERY LIMITED in scope. You will find no exposure of AFP courses related to Africa, Asia, South America (in my eyes those are the regions which will dominate AFP in the 21st century, less so Europe). Also, if you are searching for a more policy-oriented, practical curriculum, taught by former practitioners/policy-makers/etc, that is more common at DC.
Overall the students are very cohesive group. Of course, the more we get to know each other, the more we find folks we are more compatible with, but from my experience, mostly everyone is pretty friendly, outgoing, and typically, when social events are held by students, the whole class is invited. Also from my experience, the professors are very helpful and willing to meet with students. Every once in a while, professors may attend a student happy hour (though this is not common). Often you may run into some profs at the bar on the first floor, grabbing food/drink/coffee. This is a good opportunity to mingle. I found that the number of informal interactions between students/profs are not as common as the student brochure makes it out to be. That said, if you take the initiative to want to meet the profs, they are almost always willing.
The overall course selection is VERY LIMITED. This is understandable since the BC is a smaller campus, but if you know what you want to do and what you are looking for, then you may be disappointed with the course selection. Some students arrive to the BC with assumption that they can simply take the curriculum requirements and then the following year, at DC, take the courses they find more interesting. This strategy doesn't work so well since, at some point, you will have fufilled your reqts and then have to potentially choose from classes that you have no interest. When you are paying a lot of money to attend, this can become very frustrating. This has happened to me. I find myself disinterested with the course offerings, whereas the DC campus, there arent enough hours in a day to attend all the classes I want to.
The class sizes vary GREATLY. Beware of what the student brochure tells you. The core courses as well as the required econ courses will have somewhere between 35-60 students per class. The more "boutique" the course, the lesser the students. If enrollment falls below 6, the school may cancel the course. In my first semester, my average class size for four classes was 40 (2 of my 4 classes were reqd econ classes). This semester, my average class size is 33. (one as big as 72, another as small as 10).
Living in bologna is difficult to answer. For me the novelty has worn off, but that may change since the weather is finally changing for the better! Other students love living here. You will definitely get an interesting perspective to AFP (I am an AFP concentrator). The courses are taught by left-leaning professors. This combined in an environment where most of the student body leans left and learning/living in a city that is known for its left-wing political ideology and you definitely get something that you wont in DC. Is the experience valuable? I am not sure. Personally, my politics fall left of center and often I find the views, perspectives, readings, course work, class discussions sometimes ridiculously biased. Again that is only my opinion.
I urge you to contact other students if you can to get more opinions.
Hope that helps
