We got alot done all the responses were fast the internet was kinda slow but that cant be helped this was a good tutor and they taught everything clearly. - Jenifer
Excellent tutor if anyone is preparing for and exam Tutor Vista tutor would help have a better concept of how to proceed with the math equation such a brillant tutor.
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
I had appointed a personal tutor for my kid but it use to cost me a lot, so I had to look for other option, I found that Tutorvista.com offers personal tutoring at very lower price, such a relief it was. My kid likes studying here even more than the personal tutor.
