Best tutor ever. I can actually understand what to do in fraction and decimal division situations
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
This is very helpful and explains everything thoroughly. when asked to do problems slowly, tutors did them very thoroughly and even went extra mile to explain how and why with text - I just bow down to Turor Vista
You are an amazing tutor. So knowlegeable and patient. Very clear in explanations, 2 thumbs up -kelly
