Avantages
-As many have mentioned already, the flexibility in scheduling. -Are not forced to do concurrent sessions (I think some other online tutoring companies do that) -Tutor at tutor.com if you have nothing better to do with your time, or if you're desperate for the extra little money
Inconvénients
I have no clue why some reviews praise the mentor system. Your mentor rarely (if ever) offers much encouragement and berates you for the tiniest infractions. Your boss (aka mentor) suggests "improvements" for your sessions even for the very sessions I receive excellent feedback and ratings on just to hold you back from promotion and to keep you on your toes. They pay tutors the same regardless of which subjects you tutor. If you're planning to tutor chemistry, physics, or calculus, beware that the questions can be extremely random and they expect you to be an encyclopedia (when they pay so little!), so that will hurt your ratings and stats. For example, college students log in and ask upper year civil engineering questions as "Physics" and if you decline them, your stats look bad and your boss gets angry at you.
