Some courses have prerequisites which are other courses that must be successfully completed prior to taking these courses. Many beginning classes require the placement testing or completion of developmental or remedial courses before students may enroll in them.

Transfer and transient (visiting) students who have completed prerequisites courses at another institution may bring an unofficial transcript or a grade card to an academic advisor for review. If the students wish to receive credit for those courses at Sinclair, they must have their transcript sent from their former institution to the Sinclair Registration & Student Records office.
