Bachelor of Science in Biology - General Biology (120 units)

This degree major is designed for students pursuing careers that involve the study of life; it is especially appropriate for those contemplating graduate work in the biological sciences. Students may not combine this option with any other in the B.S. in Biology nor with the B.S. in Marine Biology or Microbiology as part of a dual major. This option requires approximately 80-84 units in the major, of which 47-49 are in lower division and 33-35 are in upper division.

All students must achieve at least a 2.0 grade-point average in each of the following: 1. the entire college record, 2. all units attempted at CSULB, and 3. all courses in the major.

Degree Progress

Pre-Biology majors must complete the following requirements within the specified time of declaring the pre-major. Some students may need to take courses during Summer Session to meet these requirements. Students who have not met the requirements by the required semester must either declare another major or meet with an Academic Advisor to determine if the student's performance in the courses merits an additional semester to complete.

Freshmen: A grade "C" or better must be achieved in CHEM 111A, BIOL 211, and MATH 119A (or 122) within one and a half calendar years.
