Thanks DRob!
Amanda: Unibe is a for profit university that belongs, I understand, to the Hazoury family...anyway, they have pretty good pre-med programs and the courses are given in English. It is expensive.
At PUCMM--you could study for a semester as a transfer student or through one of the semester programs run by any one of several companies such as ISA or IEEE or others...If you want, I can find out more.
Usually, you do not have to worry about transferring the credits back to your own school since you would be take courses that fit your degree program under the advice of your faculty adviser. I am kinda sure you are "majoring" in Biology, not "ignoring" in Biology. And Yes, PUCMM offers several Biology courses that should fit your course of study.
Also, since you probably need to fulfill other academic requirements, you could take a history course, a sociology course or a math course. However, first you need to check with your school and find out what their requirements are. And then you need to check with your school's Study Abroad Program office and see what they offer.
If you want to do this on your own, you need to plan on being sure you take course work that is compatible with your degree program. You will also need to find a place to stay (Here in Santiago, that costs about 18,000 a month within walking distance of PUCMM--that includes food) and plan for your other expenses...
If you have any other questions, fire away!
