Correlate Sequence in Chemistry

A correlate sequence in chemistry provides students interested in careers ranging from public health to patent law an excellent complement to their major field of study. The chemistry correlate sequence is designed to combine a basic foundation in chemistry with the flexibility to choose upper-level chemistry courses relevant to the student’s particular interests. Students considering careers in such areas as art conservation, public policy relating to the sciences, scientific ethics, archeochemistry, the history of science, law or public health may benefit from a course of study in chemistry. This correlate is not intended for students majoring in closely related disciplines, such as biology or biochemistry, and therefore not more than one course can be credited towards both the correlate and the student’s major. The correlate consists of 61⁄2 units distributed as follows:
