<p>You are correct. There are three units each semester which you sign up for during your first week of classes. The units change from year to year, but you can take a look this year’s selection here:
[ND</a> Department of Physical Education and Wellness Instruction](<a href=“http://www.nd.edu/~physedu/pe_fall_semA.html]ND”>http://www.nd.edu/~physedu/pe_fall_semA.html)
Two of the units must be “Contemporary Topics” (i.e. health), and one must be swimming, if you did not pass the swim test.</p>
