I'm not sure which healthcare career interests me the most. Do I have to decide now?
IT DEPENDS ON THE CAREER TRACK AND HOW LONG YOU PLAN TO STAY IN COLLEGE (see FAQ "What's a SuperSenior?".
For the health professions that require only a Bachelor's-level degree, such as Nursing or Med Tech or Athletic Training, deciding in freshman year is the only way to ensure that you graduate in the typical 4 years. These programs generally have pretty strict coursework schedules. See the sponsoring departments for more information.
In contrast, for the health professions that require a Master's-level or Doctoral-level degree (i.e. graduate education), the undergraduate preparation is more broad and, at the same time, fairly similar for all. A student who does his/her "homework" on career prep during freshman year can (with his/her advisor's help) create a plan of study that satisfies multiple admissions processes, leaving the student free to apply to multiple professional schools. Application is typically made 12 months prior to expected graduation from UW Oshkosh.
DISCLAIMER: No advisor can keep track of the admissions and job requirements for the hundreds of professional schools and careers out there. In addition, requirements change. It's the student's responsibility to explore the professions that interest him/her, and identify the common elements to the undergraduate preparation for these.
In general, the following are common elements of the undergraduate preparation for many healthcare professions (graduate) schools:
Math through college algebra, trigonometry, and then either calculus or statistics (sometimes both)
Two semesters of English composition (English literature does NOT count)
A year of General Chemistry, with lab, plus a year of Organic Chemistry, with lab.
(Increasingly, we are seeing a requirement for Biochemistry, too, which follows Organic).
A year of Biology, with lab.
Sometimes: a year of Physics, with lab.
Often: Introductory Psychology.
Usually: a variety of non-science courses that provide a well-rounded education (accomplished by "Gen Ed" requirements for any Bachelor's degree at UW Oshkosh).
The above list is formal coursework only. Different professions emphasize somewhat different types of extracurriculars, so these too come into play.
