Did you know that you can take OSU classes for free? Maybe you want to brush up on your calculus, learn about beekeeping or take a class on the relationships between comic books and film.

CFAES offerings include several new introduction courses to environmental science, peer mentoring in STEM, climate impacts in the Great Lakes, golf course design and management, turfgrass management, fruit diseases of the Midwest, and beekeeping.
