The Learning Center staff strives to serve the needs of students enrolled in any math course offered on the LSC-O campus. Tutoring for college-prep math courses (0301 and 0302), as well as college algebra (1314), is available on a walk-in basis. However, for tutoring in other math courses--especially higher levels--it is advisable to call ahead or arrange an appointment to secure an appropriate tutor.
