Pros
Usually they pay you on time at the ridiculously low agreed upon wage.
Cons
Sometimes they don't. Furthermore, they do absolutely nothing to support tutors when they are harassed by students. As a tutor, you are expected to simply sit there and take it if a student is being demeaning, unresponsive, or simply asking for answers and unwilling to do any work. All tutors are assigned "mentors" who seem to be mindless corporate drones that simply add insult to injury when a disgruntled student gives you an unjustified negative review. Every month or so, you are given an "assessment" by your mentor, which simply nitpicks your performance regardless of how well you're doing. Tutor.com has "guidelines" that you are supposed to keep sessions with students below 20-30 minutes depending on the subject, which is nearly impossible if it's a complex topic or if its with an unprepared student. However, mentors will harass you if you do anything to speed up the sessions by giving any sort of an answer or doing any of the steps for them.
