Biology Major Requirements (B.A.)
(Also see Requirements for a Bachelor's Degree.)
The B.A. degree in biology is designed to provide students with a thorough grounding in modern biology, with special emphasis on the molecular aspects of the discipline.
All courses required for the biology major must be taken for a letter grade (not S/U) and be passed with a grade of C- or better with one exception. The department will accept one passing grade below C- in the senior year provided that the average for all formal lecture and laboratory courses is at least 2.0.

Honors in Biology
Students completing the B.A. in Biology are eligible to receive their degree with honors.
The B.A. in biology with honors requires, in addition to the regular requirements for the B.A. in biology, a 3.5 GPA for natural sciences and quantitative studies courses, two semesters of research, a presentation of a poster describing the independent research, and a recommendation from the research sponsor.
The research requirement must be completed under the direction of a faculty member in a department associated with the Johns Hopkins University or the Johns Hopkins Medical Institutions. If the student’s research director for independent research is not a member of the Department of Biology, a Biology faculty member must serve as a sponsor and approve the recommendation from the research director.
