Ender is very talented in his teaching. My daughter was struggling with one of the Calculus concept for a whole week and with one lesson, there is an "A Ha!" moment with Ender's explanation. He is a little expensive but you get what you pay for. I rather spend the money than paying less but wasting my daughter's time to spend an hour and not learning more. Ender is also very caring and supportive, It is comforting to have him as a part of my daughter's education.
