This was my first time using this platform. I have used Wyzant many times prior. Being able to see your tutor via video allows for a better connection and communication and feel that would be a great option to have. My first tutor was not very thorough and just expected I know things and was very fast and did not break it down for my learning style. I will be trying again but with another tutor.

Alfonso was wonderful! He was able to hop right in to the labs I was doing and identify the kinds of problems I was working on. He affirmed when I was correct and helped me through some calculations so I would head in the right direction from there. Thank you for your time and effort!
