Students wishing to major in mathematics should have a strong interest in the field and normally a background of four years of high school mathematics (two years of algebra, one year of geometry, and one year of analysis or equivalent). Mathematics majors and minors fulfill their Area B mathematics requirement with the courses required for the major or minor. 

B.A. in Mathematics 

• Lower Division
  Mathematics 27, 38, 39; and
  Computer Science 21.

• Upper Division
  A minimum of eight upper-division mathematics courses is required for a mathematics major, including Math 111-112, Math 120, Math 150, and Math 193. Math 101 may not be included towards the major.

Concentration in Computer Science

A concentration in computer science should be declared by the end of the sophomore year and upon completion of Computer Science 102.

• Lower Division
  Mathematics 27, 38, 39; and
  Computer Science 21.
• Upper Division
  Nine upper-division courses (excluding Math 101) including Math 111-112, Math 120, Math 150, and Math 193, Computer Science 102; and
  Two additional upper-division computer science courses.

Bachelor of Science

A candidate for the Bachelor of Science degree in Mathematics must take in addition either Physics 1-4 or Chemistry 8-11, and two further courses from the following disciplines: biology, chemistry, computer science (except Computer Science 1) and physics. Students should contact the Mathematics and Computer Science department for descriptions of split majors with mathematics.

Secondary Teaching

All students in California planning to enroll in a teaching credential program in mathematics after earning their undergraduate degree are required to demonstrate subject matter competency in mathematics prior to admission to a credential program. Students at Saint Mary's college exhibit this competence by taking and passing the CSET (California Subject Exam for Teachers) in mathematics. Students interested in becoming a secondary mathematics teacher are advised to complete the following courses to prepare for the CSET while fulfilling the mathematics major. 

• Lower Division
  Mathematics 27, 38, 39; and
  Computer Science 21.
• Upper Division
  Math 111, 112, 113, 115, 120, 130, 150, 193.
