Admission Requirements

In the past, Biological Sciences had a very strong admission requirement of a PL1-level math placement. With the implementation of the test optional admission pathway, this requirement is no longer in place. However, achievement of PL1-level math placement can be a good indicator of strong preparation in math. After admission to Ohio University, first-year students may transfer into a Biological Sciences major if they have earned a grade of “C” or better in both BIOS 1700 and BIOS 1705 and have a minimum accumulative GPA of 2.5 at Ohio University.

For information about changing your major to biological sciences or transfer admissions requirements, view the academic catalog.

Student Success Stories

Jayanna Smith: From Small Town to Prestigious Award

Jayanna Smith won a 2024 Goldwater Scholarship, the nation's most prestigious award for undergraduate STEM students. “It means a lot because I come from a really small town,” Smith says. “Coming to a larger school, I initially found it hard to feel like I belonged here. I struggled with imposter syndrome. Winning the Goldwater gave me confidence," Smith says. "I was so scared that I would never figure out a career path. I would tell my younger self to relax and enjoy it a bit while also working hard.
