<p>This seems pretty straightforward - there are two categories of students, and you have to click the link for which category you are.</p>
<p>Category I = healthcare students, and these are students who will be interacting with the public, providing health care to them. These students are enrolled in the following programs: Medical School, Communication Sciences & Disorders, Genetic Counseling, Physical Therapy </p>
<p>Category II = everyone who is not in one of the above listed programs. </p>
<p>If you are an undergraduate, you are category II. The difference is (in general) students who will be providing health care to patients have to have some extra innoculations and/or tests. For example, sometimes they need to provide a TB test, that the rest of the student population does not.</p>
