What My Clients Say...
My tutoring clients often express their gratitude to me. I hope the comments below inspire you ~ especially if you're feeling you'll just never achieve mastery in your math or science courses!

The entire experience using C² 's tutoring service was great. Crystal was very patient and nonjudgmental. This allowed me to express and clarify whatever it was I did not understand. Her availability and flexibility regarding the meeting time and place of our sessions enhanced just how useful the service was to me.

Ms. Cubbage is a great teacher, especially one on one. The individual attention she so freely offered gave me exactly what I needed to make it through the course.

Engineering is a hard major, VERY HARD! It includes Vectors, Physics, Chemistry, and Calculus. I am an Engineering Major at the University of Tennessee in Knoxville, which is many miles away from Crystal in Philadelphia, Pa, and Crystal helped me! I am proud to be Crystal's first online pupil. Even though, Crystal was not here in person, she still helped so much. She was very patient with me and my questions, and stuck with me, until I fully understood the subject. Crystal is a brilliant teacher, and makes it easy to learn not so easy subjects.

I truly do recommend her " C² 's" Tutoring service!

Initially I was nervous about using a tutorial service, however, Crystal was extremely accommodating and comforting; she was able to pick out my problem spots and help me where I most needed it.
