<p>My son changed his schedule and he is the first one to sign up for a particular class so far. Do courses get dropped if not enough people sign up?
If this happens, is there enough time to add a replacement class or should he add an extra class now and drop it later?</p>
<p>Always add the course you want before you drop a workable alternative class. It may well be too early to see if a class would be closed due to too few students.</p>
