Curriculum outline

The Bachelor of Science in Biology degree at the University of Washington Bothell has the following Departmental Requirements:

  1. Introductory Biology Series
  2. General Chemistry Series
  3. Calculus
  4. Statistics
  5. Physics I and II
  6. Genetics
  7. Evolution
  8. Ecology
  9. Cell Biology
  10. Physiology
  11. Investigative Biology (5 credit minimum)
  12. Biology and Society
  13. Upper Division Biology Electives (20 credit minimum)

In addition, University of Washington undergraduates in all majors must complete the following to earn a degree:

  1. General Education Requirements
  2. Areas of Knowledge Requirements
  3. University Graduation Requirements

Overlapping coursework

A single course cannot satisfy more than one Departmental requirement, but it can fulfill a Departmental requirement in addition to a General Education or Area of Knowledge requirement. For example:

  • Cell Biology (B BIO 380) can fulfill "Additional Writing" (W) credit but ONLY when it is offered as a "W" course. In AUT21, BBIO 380 is not a "W" course. This WIN22 or SPR22 will be offered as "W" course.
  • B BIO 335 (Salmon & Society) can count towards either one of the "Biology and Society" or "Biology Elective" requirements, but not both at the same time. However, the class can also count towards the "Individuals and Societies" (I&S) Area of Knowledge requirement.
