+Pre-physician assistant students: In consideration of the entrance requirements for professional programs, pre-physician assistant students may opt to replace Comparative Anatomy & Physiology (BIO 227 and BIO 228) and the corresponding labs with Human Anatomy and Physiology (BIO 211 and BIO 212) and the corresponding labs.
^Independent Study in Biology:
- Within any student's declared concentration, the student may take a maximum of four credits of Independent Study/Research (BIO 498 or BIO 499) to be counted as an "elective" within the concentration.
- Within any student's declared concentration, the student may take an additional 1-4 credits of Independent Study/Research to meet the maximum of eight credits allowed provided he/she receives preapproval from the concentration faculty. The additional four credits can be applied only to the "open electives."
- Students who have declared in one concentration may take an additional one to four credits within another concentration. These credits can be counted only as "open electives." The credits may not count as "biology non-concentration electives."
