There is a paging feature at the bottom of the possible matches list on your user dashboard. Use this to review more possible matches.
Also, you can change your current list of matches by retaking the matching survey and altering/widening your answers. This will create new matches and make adjustments. As mentors are being added to the system, your list will be updated with the best match.
If you want more options than what is appearing for your selection, speak with your program administrator.
