<p>Some of the same class, offering the same credits, have like 5 hours each week, then some have 10 each week, and 3 hours each week…
Do the hours matter?</p>
<p>They all last the same period of time, but some classes have more hours.</p>
<p>Hours do not matter, only units. Some classes are just longer than others,depending on the subject matter. Usually, if it is a significant difference there will be an increase of units in that course, but not always. Good luck to you! :)</p>
