<p>I was looking at my weekly schedule just now and it seems I have an added extra something I didn’t sign up for. It’s called Phys 1B on Thursdays 7:00-8:50 at wlh 2005 and instead of “LE, LA, and DI” (lecture, lab, dicussion) it’s called “PB” and the section is called “weekly” instead of “A00, C07, etc.” Is this some kind of problem/review session for phys 1b and am I forced to attend it?</p>
<p>yes it is, and no you’re not forced to attend. the TA(s) just go over problems/questions…it’s really not worth attending, imo (then again, i went to 1A’s PB once…for 5 minutes…left after the TA was explaining what sin, cos, and tan were…)</p>
