<p>there are 6 different units (3 for first semester and 3 for second semester). For everyone, two of those units are taken up by Contemporary Topics. If you fail the swim test (search for all threads about this if you have any questions) then I believe two more units are taken up by a swimming class. </p>
<p>Depending on how you do on the swim test, you then get to choose 2-4 units throughout the year. Different classes are offered at different times and in different seasons of the school year. </p>
<p>If you like a good work out, I highly suggest cycling if you can get Skube as an instructor.</p>
