it is incredibly hard to write on the board with a laptop that doesn't have a mouse. If there could be an added feature to type equations that would be perfect.

Thank you for taking your time with these couple of problems. For the first one i liked breaking everything down a lot! For the second one the clarity on the differentiation and redouble checking was something i would not have gotten! Thank you for your patience with me!

Tutor.com is incredibly helpful. When I’m doing my math homework and get stuck on a question, I go to tutor.com and it’s great to get an explanation from someone with experience. I don’t know what my grade would be like without it.

Today's session was helpful but I wish the white board function was better :( I have to write everything using the mouse which is especially difficult when doing calculus tutoring. It also would be nice if the student could add pictures to the white board without having to send the file to the tutor every time.

I really liked how he was fast and accurate with giving me advice and describing how to solve the problems. I really liked how he was engaged and knew what he was doing and he also asked questions about what I was doing. I would really recommend him to others and I think he was by far one of the best tutors.
