One of the following organic chemistry courses:

  • CHEM 203 and 207: Organic Chemistry I with Lab*
  • CHEM 171 and 173: First Year Organic Chemistry I with Lab*

*Satisfactory completion of CHEM 171/173 and 172/210 first year organic chemistry series with labs in conjunction with AP credit for CHEM 131 fulfills the chemistry requirements.

  • STAT 190: (formerly STAT 213) Introduction to Statistical Methodology

Upper-Level Writing (ULW) Requirements (Two Courses)

All biology majors must complete two ULW courses. Although students are strongly encouraged to complete both ULW requirements by taking biological sciences courses (BIOL, BCH, MBI, NSCI), an upper-level writing course within a natural sciences discipline may also be used to meet one of the requirements.

Biochemistry majors are also welcome to take CHEM 210W: Organic Chemistry Lab II to fulfill part of this requirement. All other majors need permission from their biology advisor.

Writing courses within the humanities and social sciences cannot be applied to the biology major. See the upper-level writing requirement page for more information on which courses satisfy this requirement.

Preparing for Medicine/Health Professions

Graduate and medical degree programs in the health professions frequently have admissions requirements that include two semesters in general chemistry, organic chemistry, general physics, and calculus. Some programs may have additional requirements such as biochemistry and/or microbiology.

For detailed information on premed course requirements, academic planning, and the MCAT, visit the Health Professions Advising website.
