A minor in college is a course of study that the student has studied intensely, but not so intensely that he or she can claim it as a second major. The requirements for a minor vary by university, but roughly, a person takes one-half to two-thirds of the courses in a field that would be required for the major. For example, Patricia is a Biology major, and takes 60 credits in Biology. She also takes 35 credits in Physics, qualifying her to graduate with a major in Biology and a minor in Physics. If Patricia takes 25 more credits in Physics (bringing her up to 60 Physics credits), she can graduate with a double major in both Biology and Physics.
