Two Days a week, or three?

<p>What is the major difference between taking a class that meets three days a week as opposed to three?
For some of my courses I can choose MWF or TuTh, and my first guess was that the two days a week would be more summarizing than instructing.</p>

<p>There’s not a difference like that. It’s just that a given sitting of a TuTh class is longer than a given sitting of a MWF class.</p>

<p>like for MWF class, it lasts 50 mins (for example, 10:00-10:50AM)
while TuTh is 80 mins like 2:00-3:20PM</p>
