You are required to declare a major before your junior year. However, in
biology it is strongly recommended that you declare your major as soon
as possible. One reason is that a large number of introductory course
are required to complete a biology degree. If you do not take
introductory classes right away, it may take longer than four years to
finish. When you declare your biology major, you will be assigned an
advisor who can help you with course scheduling.
