fitchpath, I would assume that they are in Spanish, since classroom instruction will be in that language. The class I attended last year in UCC was being held in Spanish.
Albah, Ponce DOES accept it if you take your Spanish classes in the summer, that's what I did last year and it worked out for me, just be sure that you have the 6 units completed by the end of the FIRST summer session, since orientation starts in July. I know it may sound difficult, taking 2 upper division Spanish classes at the same time, but it something you have to do. As far as the DO vs. MD descision, that is something up to personal preference and where you end up practicing (from personal experience and what I've been told), however, I really enyoyed the atmosphere in Ponce, the town is really cool and it is not as busy as the San Juan metro area. The level of instruction appeared on par with the other mainland schools that I have interviewed at , and contrary to some opinions, you can enter whatever field you want to from Ponce. I know an ortho. resident in Ohio that came from Ponce, and there is always the option to transfer to the mainland after the first two years. The students are nice and there is a general atmosphere of cooperation between them. Adamant might be able to explain more about life in Ponce and how the classes are run since he is there right now.
Tristan, no idea how they pick the interviewees, but last year I was interviewed in March and they informed me basically the same stuff that is in the MSAR. They do prefer their students to have ties to the island though, but I know of students that have been accepted that don't.
Good luck guys!
