I spent one month studying Wolof, French, and cultural studies at ACI Baobab through George Mason University in the summer of 2007, and it was one of the most fantastic abroad experiences I ever could have hoped for.
The staff at ACI Baobab was incredibly supportive, our classes were well run, and we hardly ever were lacking for great activities, excursions, or courses.
Our host families were fantastic as well -- I ended up being paired with a family that had two daughters my age and a 4-year old nephew (who, by the way, kicked my butt at dancing... naturally). In true Senegalese style, they welcomed me into their family and -- years later -- hope to see them again some day :)
Also, their cultural training before the start of our homestay was incredibly helpful and just another reason why I'd rank them as supportive and fantastic with their academics!
What would you improve about this program?
Hard to know at this point if this was part of our orientation or not, but a little run down on how to deal with *ahem* stomach issues (before they happened) would have been helpful.
