Best times to register for classes?

<p>when are you most likely to find slots open in classes you are trying to register for?
BIO 311c is in high demand...i haven't seen anything open up for a week...
any suggestions on when it would be best to check?</p>

<p>It's supposed to open up some every Friday morning at 8am according to what I read in some threads. I tried this morning but all the classes I want to sign up are still all closed or waitlisted.</p>

<p>^ Same. Did you see any classes reopen at all?</p>

<p>I did see some reopen around 9am this morning. I was able to get in one.</p>

<p>^^^D got up at 8:00 to try to change a History class and had no luck. I am wondering what kind of classes will be left for future orientations.</p>
