<p>To clarify, Reed doesn’t refer to “credits” but instead to “units,” which are equivalent to 4 semester credits or 6 quarter credits (in quarter system).</p>
<p>So a student taking 4 units is taking the equivalent of 16 credit-hours under the semester system.</p>
<p>On the initial question about work: a few hours per week is managable (I did it), especially if it’s on-campus. I wouldn’t plan on more than 10 no matter what.</p>
