I found WyzAnt through a Google search when I was in desperate need of help in organic chemistry. I emailed several tutors through the site, still not exactly sure that I'd even get a response. Within hours I had heard from three tutors and I settled on a young lady named Sana. She was $40 per hour which trust me is a great deal in NYC, especially for an Ivy League educated medical professional who travelled to my neighborhood, Union Square, for no extra charge. It was very helpful to be able to speak with Sana before making any payments or commitments. When I was ready, I added a credit card to the website and after the lessons I got an email from WyzAnt with my lesson details and the amount charged to my card. The combination of the tutor selection, price, quality and simply payment mechanism makes WyzAnt a great choice if you need a tutor. I would highly recommend the company and its tutors.
