<p>...the class? I don't want to drop anything unless I know I can switch. Is this possible?</p>
<p>Almost always, it doesn't matter which lecture you go to; just go to the one you want. However, you can modify both of these without dropping. Go to Just the Facts (not the website but the one through Bear Access installed on your computer), click Add/Drop, click Course Requests, then select the course, then click modify, then find your desired section time, then click save. That should enroll you in the section you want, provided it isn't full.</p>
<p>Hmm, I can't find a way to switch the lecture time using that method, and it is blocking a class I want to add.</p>
<p>Like I said, lecture times almost always don't matter. What class is this? And what message does it give when it won't let you add?
The other thing you could do is just drop and try to add at some really obscure time so you don't risk losing your spot in the original class if you don't get into your desired time...</p>
