As a mentor, I do find it very difficult sometimes to find items for my students to review. Luckily, i have some wonderful students who will grab their own items from their points or just purchase items while we wait. This helps to get them going on reviews and possibly graduated sooner--if they are ready.
I am not going to have an opening for awhile, the 38th I think--my next class is reserved by someone I just had to turn down since they were the second applicant in line. You could spend the time messaging some mentors to find one who would work for you. Good luck, I look forward to seeing you around the site and if you have any questions feel free to message me as well.
