Program Director: Dr. Lena Garrison Phone: 410-386-8468 Email: This program provides students with the background necessary for transfer into a four-year institution's biology program. The courses in the program are transfer oriented and form the basis of a solid foundation in the liberal arts. By using ARTSYS, at, or the transfer institution's catalog, students will work with an academic advisor to create an academic plan leading to graduation and transfer. The second math course taken by students depends on their transfer institution. Students transferring to UMD or Towson will need MATH-132. Students transferring to UMBC, McDaniel or Stevenson's Biotechnology program need MATH-135. Students transferring to Stevenson's Biology program need MATH-115. Arts and Humanities recommendations: Stevenson University recommends COMM-105. UMBC requires a world language. Towson does not accept BIOL-215 as a majors course; see Dr. Garrison for a recommendation/substitution. The following courses are required for this concentration; some courses fulfill General Education requirements: BIOL-101, BIOL-102, BIOL-215, BIOL-240, CHEM-105, CHEM-106, CHEM-201, CHEM-202, MATH-123 or MATH-130, and MATH-115, MATH-132 or MATH-135.
