Should I list classes that I plan on taking at my local community college (dual enrollment), but which I am not yet registered for (I can’t register until a few weeks after the UC deadline for Winter, and mid-March for Spring)? (I am not by any means guaranteed to get the class—it may be full).
If your actual spring course work differs from what you reported on the application (whether you add or remove courses), then you should update the schools when you are sure of the change.
