Students must obtain a grade of C or better in all prerequisite courses to fulfill the prerequisite requirements for biology courses. To be eligible for the B.S. degree in biology, students must have a grade of at least C for all biology courses applied to the major, and must successfully complete the Major Field Test in Biology as a departmental exit exam. The minor also requires a C or better in each course. Students should be aware that 3000-4000 level biology courses may have prerequisites which could increase the total credit hours for the biology minor beyond 18.
