Our Programs

The Mathematics Major prepares students for careers in secondary mathematics education and for further graduate study in mathematics, statistics, and related disciplines. A major or minor in Mathematics complements a secondary major in any area, especially science, business, data science, and intelligence studies.

After completion of the bachelor's degree in mathematics, students interested in secondary education may enroll in the one-year Master of Science: Pedagogy and Practice program here at the University and earn a master's degree along with teaching certification.

ALEKS Math Placement

The ALEKS Math Assessment ensures students' readiness for particular math, statistics, and chemistry courses at Mercyhurst. Since these courses require the mastery of prerequisite material, it is important for students to begin in the course most likely to lead to success. Students will not be permitted to take a course unless they have demonstrated readiness. After completing the initial assessment, students who wish to improve their skills may use the included learning modules.

Tutoring Information

Drop in tutoring for College Algebra, Trigonometry and Functions, Mathematics for the Natural Sciences, Calculus I, and Calculus II is available through the Mathematics Department. You do not need an appointment - just stop by with questions for our student tutors.

A personal tutor may be arranged for these and other classes through the University's Tutoring Center.
