The Department of Integrative Biology offers a Zoology major and Biology Minor online, as well as a wide variety of Biology and Zoology online courses. A few courses, most notably BI 204, 205 and 206, are restricted to Ecampus majors to ensure course access. Newly admitted online students must do an orientation through Ecampus student services before they meet with a major or minor advisor to register for online courses.

Online students, both degree and non-degree seeking, must meet the equivalent prerequisite requirements to Corvallis campus students. Students can review how their courses may count at OSU by looking at the OSU articulation tables. Students who have questions about their program or how courses might count for requirements or course prerequisites should first work with Ecampus student services.
