Undergraduate Biology and Marine Biology majors should see a Departmental Advisor (below) if your question pertains to:

• Specific Biology course requirements
• Petitions
• Exceptions
• Biology transfer evaluations
• Prerequisites for Biology courses

For general advising pertaining to the UO requirements, or pre-health advising, it’s recommended you see an advisor in Tykeson Hall.

Frequently Asked Questions

1. Can I take Biology courses pass/no pass and still have them count for the biology major?

Yes, biology majors can take most courses pass/no pass, including those required for the biology major. However, keep in mind that you can only take 12 credits pass/no pass out of 180 credits. If you go over 180 credits then you can take more credits pass/no pass. The university requires 168 graded or P* credits.

2. Do I need to complete an emphasis area if I major in Biology?

No, you are not required to complete an emphasis area for the major. However, we do recommend emphasis areas because they enable you to focus on a certain aspect of biology. The emphasis areas are: Marine Biology, Human Biology, Neuroscience & Behavior, Ecology & Evolution, and Molecular, Cellular, & Developmental Biology.

3. What lab sequences are required for the Biology major?

General Chemistry Labs (CH227, 228, 229 or CH 237, 238, 239) are the only labs required for the biology major. However, if you are pursuing a career in health care (e.g., dentistry, medicine, etc) or planning to attend graduate school, Organic Chemistry and Physics labs may also be required. If you are unsure, check with UO Health Professions Program and/or graduate school of interest.

4. What is the difference between Math 246/247 and Math 251/252? Which one do you recommend?

Math 246/247 is Calculus for Biological Sciences I & II. Math 251/252 is General Calculus I & II. For biology majors, we strongly recommend that you take 246/247 because of its applications to biology. However, both of the sequences fulfill the requirement for the biology major.

5. How do I get into a research lab?

Please visit Undergraduate Research in Biology to learn more information about this process, and come see us in the Biology Advising Center (Klamath Hall 65) with follow-up questions.

6. What are the differences between a Marine Biology major vs. a Marine Biology emphasis?

In order to earn a degree with a Marine Biology major, you need to spend at least three terms, 12 credits per term minimum, at the Oregon Institute of Marine Biology (OIMB) plus fulfill all of the major requirements. Students majoring in Biology, General Science, Environmental Studies, etc. may earn an emphasis in Marine Biology by spending a term at OIMB and taking the required emphasis courses.

7. I’m in the Clark Honors College and a Biology major.  Do I have to take both HC 477H Thesis Prospectus and BI 403 Bio Honors Thesis?

If you are a Biology Honors student, you need to choose from either the BI 401 Research (4 credits) or take the year-long BI 403 (Bio Honors thesis) during your Senior year, HC 477H cannot substitute this Biology Honors course requirement.

8. Can I count BI 401 research credits towards my upper-division credits?

For Biology and Marine Biology majors, you may apply a maximum of four credits of BI 401 Research to be applied towards the elective Biology upper-division credits. In addition, two terms of BI 401 in the same laboratory is equivalent to one Lab/Field course.

4-Year Plans

Sample 4-yr plans for the Biology major listed below are based on initial Math placement. Prior to taking the exam, students are encouraged to study problems on sites like the Khan Academy. Preparation and retaking the exam has improved individual placement considerably. There are a number of possible hybrids for the below plans, any of which can include premedical preparation and research. For details on premedical and other allied health programs, please see our outstanding Health Professions Program.
