What's up with all the prices?
I think http://www.wyzant.com is doing a great job bringing together students and tutors. Even though some tutors charge up to $70/hour and higher, it is hard to see my qualifications until you try. Therefore, I charge $25/hour so that the potential students would try me out and see how good I am on the background of professors and teachers. I am trying to bring affordable tutorials to my students for them to know that good tutors are not the most expensive ones.
