Biol 638 now requires a C or higher in Chem 335 and a C or higher in Biol 636. This change primarily affects students pursuing a degree in a BA in Biochemistry, BS in Biochemistry, or BS in Microbiology, or any student planning to take Biol 638 as an elective. If you plan to take Biol 638 in the Spring 2020, you should complete Chem 335 either this spring or summer with a grade of C or higher. Chem 335 is unfortunately not offered in the fall semesters at KU. Biol 636 also requires a grade of C or higher for Biol 638, and is offered in fall semesters. Biol 638 is offered in spring semesters.
