<p>Does it make sense that I signed up for a discussion class before its lecture? I have the discussion at 11 AM and then the lecture at 3PM, but I don't get how you can have a discussion without having the lecture first</p>
<p>I’ve seen it work two ways.
One: the first ‘discussion’ may be canceled by the TA or used as an opportunity to do introductions and it is just like any other section, so really it just goes over what you did in a previous lecture, which could be nearly a week prior depending on the lecture schedule.
Two: the TA will get ahead on the material a little bit, supplementing lectures (or as a mix of option 1 and 2).</p>
