<p>Without having done the sort of research mamenyu suggests (which is a good idea), my instinct is to say that she should still easily be able to graduate in four years without taking any science courses this spring. Many students do not take courses in their major all eight semesters (for one thing, many students do not decide on a major until their sophomore year). The sciences are a little more restrictive, since courses often need to be taken in a particular sequence, but it should almost certainly be possible. I suggest she talk to a Biology faculty member for reassurance.</p>
