Chemistry, Physics and Mathematics Requirements
In addition to Chem 111A-112A and the accompanying laboratory courses Chem 151-152, biology majors are required to take Chem 261 and either Chem 262 or Chem 401; Physics 117A-118A (or Physics 197-198); Math 132 (Calculus II) and one of the following: Math 2200, Math 233, or Math 3200. Courses taken in University College, Washington University's evening school, do not meet these or any other major requirements. Students who plan to take physical chemistry must take Math 233 (Calculus III). Math 2200 or 3200 (Elementary Probability and Statistics; required for tracks in Ecology and Evolution track and in Genomics and Computational Biology, see pp. 4-5) and Math 322 (Biostatistics) are valuable, particularly in research.
Majors ordinarily begin work in biology with Biol 2960 in spring of freshman year*. After completing Chem 111A-112A and the accompanying laboratories Chem 151-152, also taken during the first year, students proceed to Biol 2970 and then upper-level classes in the sophomore year, accompanied by organic chemistry (Chem 261-262). Biol 2960 and Biol 2970 are required for majors and appropriate in sequence for premedical and predental students with other majors.

Advanced Biology Requirement
At least eighteen units in advanced Biology courses (numbered 300 or above) are required. These eighteen units may not include Biology 303A, 307A, 374, 387, 388, 393, 487, 488, cross-listed courses originating in other departments (except Biol 360, 4202, 4580, 4810 and 4820, which count as biology major credit despite external origins), or more than three units of history-of-science courses. At least one of the approved advanced laboratory courses in biology must be completed. At least one course in each of three distribution areas (A-C) and an advanced laboratory course must be taken; each of these courses counts toward the required 18 advanced biology units. Up to 6 units of Bio 500 may be counted toward the 18 advanced biology units.
An upper-level laboratory course chosen from the following list is required for the biology major. Students planning to pursue research careers in the biomedical sciences are strongly urged to take additional laboratory courses. NOTE: Biology 500 does not satisfy the laboratory course requirement for the biology major.
