<p>I'm an incoming freshman for Berkeley and I had a question regarding registering for classes. Is it ok if one were to sign up for a discussion section that has a different number than the lecture section? For example, I want Chem 1A (01 Lec), but for discussion, I have chosen 301 DIS. What about if I choose Chem 1AL 03 Lec but with a lab section 800 LAB? Thank you for your help.</p>
