The Learning Strategies Center provides free peer tutoring for all Cornell undergraduate students in about 50 courses. You can find more info about tutoring here. Most LSC tutoring is offered on a drop-in basis, you can find the full tutoring schedule here. This semester, in some of the courses we support, LSC is piloting the opportunity to make an appointment ahead of time. The tutoring schedule has more information about tutoring appointments. In the future we hope to expand and have more appointments available for more classes.
