georgetown ABSN question

Here is what I've been told about the international health certificate: It is somewhat like a minor (4 classes). So, the way Gtown's ABSN program is set up, you need a certain number of prereqs for entrance from their specified list, then you take a few remaining ones (that you didn't take from the list) during your program. However, for the intl. certificate, you need to complete a few more prereqs BEFORE entrance b/c you will be taking the four intl. health classes while non-certificate students will be taking whatever prereqs they didn't take before entrance (i.e. philosophy, religion, etc). I'm interested in the certificate, too, and may pursue it if accepted. Sounds confusing, I know.
