The B.S. major in Chemistry that is certified by the American Chemical Society requires 47 credits in chemistry courses and an additional 33 credits in mathematics and physics. A non-certified chemistry major can be earned with as few as 30 credits in chemistry and 16 in mathematics and physics, which is a popular option for students desiring to combine chemistry with a second major or minor, such as biology, mathematics, computer science, or physics.
Double majors require very careful planning.
