<p>Hello, I am taking PHYS 5 (The Universe) and when I enrolled in the class the discussion times were TBA. The professor emailed me back saying that the discussion section times are Wednesdays 3:00-3:50. Unfortunately, this overlaps with one of my other classes. I was wondering how crucial it was to attend these discussion sections?</p>
<p>I really don't know what a discussion section is and how it is any different than a lecture; so if anyone could explain that to me that would be awesome. Are tests administered during discussion sections? Is it something I can miss if I am able to record whatever goes on in class?</p>
