<p>If you ask permission, you will get it (therefore the answer is 100%). For most (if not all) UHC classes, there is no cap of students-- if many students enroll they will find a space big enough to fit them. However, the nature of UHC courses tends to keep class sizes small (for instance, my UHC Chem 1 class was about 120 students. My UHC Chem 2 class was 49).</p>
<p>As for whom to ask: Just email one of the UHC Advisors. Their emails should be up on the website.</p>
