Half of the positive reviews seem pretty fake here... I tried Wyzant for 3 months and this service makes no sense. The tutors are forced to give 40% of their rate to the site so they totally overcharge students and parents and clients are forced to pay through website... why?
Anybody can open an account as a tutor, so there is no exclusivity or warranty...
Also... I realized that parents giving good reviews here (which seem pretty fake) acknowledge that the site is abusive towards tutors and they basically show to not care which is even worse...(flash news... you are being overcharged because of these practices!)
I closed account and use care.com and Tutorz. Way better!
