I'm a PhD student in mathematics, and I was looking around for a way to make some extra income on the side through tutoring. I was finding hardly any work until I made my WyzAnt profile. Soon I had more clients than I could even see! I've now clocked 200 hours working for WyzAnt which means I now get to keep 75% of my fee. Granted, that means WyzAnt is still taking 25%, and that's a lot of money, don't get me wrong. However, it's entirely worth it, for two reasons: (1) I find so many clients through WyzAnt that I can fill my schedule and (2) I save tons of time - I waste no time advertising myself and billing clients; WyzAnt does all that for me. Put it this way: if it wasn't worth it, I'd have stopped long ago.
