Prospective STEM and Environmental Studies Majors

In order to explore or pursue some majors at Lewis & Clark, you must start on the path in your first semester of college. That is because courses in the Computer and/or Mathematical Sciences, Environmental Studies, and Natural Sciences are very sequential. Many classes are offered only in the fall, so if you wait, you could be set back on a major for an entire year.

  • If you are considering a major in Computer Science, Biology, Biochemistry & Molecular Biology, Chemistry, Math, or Physics, you should take one or two math or science courses in your first semester.

Before anything else, you must demonstrate a proficiency in algebraic math in order to be eligible to register for introductory level STEM classes. This can be done by:

  • scoring 53 or higher on the ALEKS placement exam
  • scoring 4 or 5 on the AP AB or BC Calculus exam
  • scoring 5, 6, or 7 on the IB Higher level Mathematics exam
  • transferring in a college course that is equivalent to L&C’s QR 101: Quantitative Reasoning course, or higher

To learn more about the algebraic math prerequisite and the ALEKS assessment, visit Placement Exams.

If you have college-level Transfer Credit or qualifying AP or IB scores, please submit previous college transcripts or exam scores to L&C prior to registration, as these may impact registration for STEM or Environmental Studies majors.

The following courses are recommended for prospective STEM or Environmental Studies majors:

Note on registering for classes with a separate lab: Science classes in Chemistry, Earth Systems Science, and Physics have co-requisite courses, which means that you must register for both lecture and lab sections simultaneously (in fact, WebAdvisor will not allow you to register for one or the other on its own). For example, if you are interested in taking General Chemistry, you can register for both CHEM 110-01, a lecture section, and CHEM 110L-03, a lab section (or any lecture and lab pairing that fits with your schedule).

Advice for the majors above is also on this handout, as well as advice for students interested in the Health Studies and Neuroscience minor.
