Total credits: 120
Credits at CSUMB: 60
Credits in the major: 72 - 82, depending upon the concentration. At least 40 units must be upper division, but not all of these need to be in the major.
The Biology major begins in the freshman year with specific requirements because most upper-division (junior/senior) biology courses require lower-division (freshman/sophomore) courses as prerequisites.
Like other majors at CSUMB, the Biology major is defined in terms of a set of Major Learning Outcomes (MLOs), which are things you'll be able to do after completing the major. Each of the three concentrations within the Biology major uses a slightly different set of courses to help you achieve the same outcomes in different ways. For details, check out the course requirements for each concentration.
