He is an excellent tutor, he knows very well all the math topics, I definitely recommend him for a math tutor.
Not only did Christopher help my son greatly with his Calculus 2 class, he is also timely and reliable. I would highly recommend him for a tutor.
I am very impressed with Samuel. My son has some anxiety problems, both with people and also with school work. Samuel was very patient with him, and my son had a great lesson and was very happy. We will continue to work with Samuel as long as we need tutoring.
