Tutors in both departments have short forms available that can be signed and given to students, giving the date, name of assignment worked on, comments, and any follow-up recommendations they have. If you need one of these to get credit with your instructor, simply ask your tutor to provide one.
Note: verification slips are only given to students who show they are engaged in the tutoring process. If you simply show up, tune out, and make no notes during the tutoring session, the tutors are unlikely to sign a slip.
