There are no special requirements to be admitted to Biology or Zoology beyond what OSU requires. Transfer students should read the OSU Admissions Transfer Students Page which covers general policies' and provides tables of approved transfer course articulations along with information about the Degree Partnership Program and transfer degrees such as AAOT, DTA and IGETC. Students transferring from schools in Oregon should use the Oregon Community College Transfer Guides with their community college advisor. Students coming to OSU from other schools should discuss the four-year plans outlined in the the Biology or Zoology Advising Guides (genearlly track I) and the OSU Admissions articulation tables with their community college advisor.

Students should begin taking math and science courses before transferring to OSU, particularly math and chemistry. Students who wait to take these courses may have a more difficult transition and extend their total time needed to complete a degree. Generally, transfer students should complete the entire series of any science courses before transferring as series courses may not work if only partially completed. Transfer students who choose to take biology should take the introductory, year-long biology series for majors with a lab and should not take non-majors courses. The same is true for chemistry, physics and organic chemistry, though students should review the organic chemistry transfer policy. Most transfer students do not complete physics before transferring.

All students transferring to OSU (including Degree Partnership students) or changing campus within OSU (moving between Corvallis campus, Cascades campus or Ecampus) are required to attend an orientation for their destination campus before registering.
