<p>The best thing to do is look at the biology major in the catalog (available online), which will tell you all of the requirements for the major, and also look at the schedules of classes for this year and last (also online), to get a notion of how often courses are taught - there may be some courses that are only taught once a year (for example, many entry level courses in languages are offered only in the Fall). With all the good advising in the world, it is a good idea for students themselves to map out the requirements semester by semester, to avoid future surprises.
