I found First Tutors through the recommendation of a friend who had used them for her children. I have used them four times over the last 5 years and have found 4 excellent tutors who have taught my daughter. The website is easy to use and the reviews were reliable, I can only say the tutors I picked were heavily influenced by other people's reviews and all were as good as other people had said. I would recommend them to anyone as the site gives enough information to make a decision without the pressure of contacting people directly. I feel the charge for the introduction service is reasonable, no registration charge, you just pay for the tutor contact you choose.
