<p>Well... generally, to be able to register for any course that requires prereg, you have to finish the prereg[s] before you can take it. For example, taking upper division courses that require lower division courses, you have to finish all the lower division first. I think you are overconcerned about graduating late which would cost you more right? If so, just relax, in your first semester at your new school, you will meet with an adviser or counselor who will help you specifically how to make an education plan and how to achieve your first Bachelor degree. </p>
<p>Also, since you take many courses already, the school decisions are mostly depend on your GPA then.</p>
