"C.J. Hellwig is an enthusiastic and adept tutor. As a condition of my acceptance into a graduate program, I needed to take a college level algebra course and attain a grade of B+ or better. C.J. tutored me twice a week and in all reality, taught me the material start to finish, since I was taking an on-line course, there were no 'classes' to speak of. I received an A in the course. Without C.J.'s well thought out and creative explanations, encouragement and insightful analysis of the material, I doubt that I would have met the condition of acceptance to my program. I highly recommend C.J. as a tutor for any subject, he is calm, organized and a true professional."

"I am a graduating senior at NEST + m High School (New Explorations into Science, Technology and Math). Thanks to C.J.'s comprehensive understanding of mathematics and science, I've been able to keep an average above 90 in physics, chemistry, algebra, algebra II, trigonometry and geometry. I've been using him for three years and he's not only flexible and willing to arrange new sessions on short notice, but he also carries his own supplies and a seemingly endless supply of problems for any mathematic or scientific subject."

"C.J. is a remarkable tutor, patient, kind and bright but even better able to take complicated concepts and boil them down to understandable pieces of information. He took the fear out of an advanced statistics class for me helping me figure out what was essential to know."

"C.J. worked with me for two semesters in Calculus I and II. I was very far behind in my math education, and CJ helped explain the material in such a way as someone in my position could comprehend. As a result, I actually learned something in these classes, and managed to get much better grades than I would have otherwise. Thanks C.J.!"

"C.J. has been tutoring my fifth-grade son for six months now. He makes everything fun, and my son loves and looks forward to working with him. Because of C.J., my son has improved greatly in math, and confidence has also improved. I would highly recommend C.J. for any tutoring needs you may have."

"C.J. was a great tutor. I had no clue about Business Statistics. In the end, not only did I end up doing very well in the class, I actually understood everything because of the clear, simple explanations given to me. Thanks!"

"C.J. is a very competent and patient tutor who can explain complicated concepts in an understandable way. He was always available for questions and flexible with his schedule. I would highly recommend C.J. as a tutor for any subject."

"I am currently a post-bac student looking to apply to Dental School. When I first started taking courses at Hunter, I hadn't taken a math or science course in eight years, and I was having serious trouble with the material. I have been meeting with C.J. for over a year now, and since then I really understand the material and feel much more confident in my abilities. I received an A in first-semester chemistry and presently hold a 3.7 GPA/ I would highly recommend C.J. to anyone who needs help in any science and math class. He is extremely patient, encouraging, and insightful. With C.J.'s help I can now say with confidence that I am on my way towards my goal."

"CJ is one of the best tutors with which I have ever worked. He makes even the most difficult of material clear and easily understandable. Not only does he explain the problem, he fully describes the reasoning behind the answer! I feel so fortunate to have had him there to help!"
