Why do some sections of lectures have more class time?

<p>Im looking at taking a physics course this fall and I noticed that one lecture meets 4 times per week, 1 hour per class. The other lecture meets 5 times per week for 1 hour per session.</p>

<p>Both professors have great reviews.</p>

<p>Do these classes take the same exams? I don't know if it would be worth it to take the section with another hour per week.</p>

<p>*Also, the section that meets more says it requires department consent to enroll so I guess ill go with the one with less class</p>

<p>I think thats a CSP section or whatever that weird program is called</p>
