If you are a pre-health professions student (e.g., pre-med, pre-dent), you should take the prerequisite science courses for your field at Marquette.
You should also discuss your study abroad plans with one of the pre-health professions advisers:
College of Arts and Sciences Pre-health Adviser
Sensenbrenner Hall, 005
College of Health Sciences Pre-health Adviser
Schroeder Complex 244
Please note that graduate-school entrance exams and interviews may influence when you decide to study abroad.
