<p>My preview advisor (the professor not the student) told me I can add/drop classes starting August 9, but I thought we couldn't do that until the first day of class?
Just wanted to clear things up, thanks</p>
<p>If you are registered already for 15 hours, ISIS may not let you get back in until a future date, perhaps August 9th. I think even if you can’t in until a future date you can still drop classes. Just try. If it lets you in now to register, you can add and drop freely until the end of the first week of classes.</p>
