Hopefully this doesn't come off as a whining view, but my experience with physics lab was horrible in undergraduate.
There was such disconnect between lecture material and the stuff we were trying to do in those lab courses. Many times, labs were followed by a mini-lecture by the TA because even they acknowledged that, some of the stuff in the lab are not covered by the lectures. That's why I hated those physics labs, and more reasons why I'm not looking forward to it. BUT, if that's what it takes, then that's what it takes.
I have similar opinion for Ochem labs, you just sit there for 4hours boiling stuff.
