People, students do not come to Madagascar to study any more than than people visit Madagascar for medical tourism unless you are interested in voodoo. Anyone, a student who can afford to leave the country for a higher education do so and go to France mostly.
University here is a mix of language of French and Malagasy at University level, so broken French usually and rarely on the intellectual level- Depending on the region being there are 18 different dialects and less developed levels in French- Tana university being the best. I hired a college student out of the main university of Tana and when I thought I could talk with him about the stars in the skies and mentioned what he thought about if there was life in space being that each star was a sun, he said that stars are not suns or why didn't they look like our sun?? I let that conversation die off.
