Testimonials

"I called C.J. initially for help in chemistry as I was a postbac student looking to go to medical school. I wound up seeing him steadily for physics, organic chemistry and eventually for all of my MCAT studying. He was punctual, amazingly knowledgeable in all the subjects, patient and very easy to understand. I'm proud to say I've been accepted to medical school and I owe a large part of that success to him. My recommendation could not be stronger."

"C.J. Hellwig is my go-to guy for everything math or science related. He will talk you through any problem, no matter how seemingly obvious or difficult. He's always prepared, really friendly and knows what he's talking about. Without this guy, I definitely would've failed chemistry. I don't want to speak too highly of him, but C.J. is nothing short of a miracle worker. I can't recommend him highly enough.
– Ari Anderson

"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."
– Bill L.

"C.J. helped me understand concepts in just minutes from Professor Shaevitz' Physics I Course at Columbia University that I would otherwise never have understood. Even though he started tutoring me in the middle of the semester, meeting with C.J. improved my grade significantly, and I actually retained the material as opposed to forgetting it once the course ended. For anyone struggling with physics or any other subjects, definitely contact C.J.!"
– Marielle Johnson

"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. 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 the best! I would never have done as well as I did in my Chemistry I course with Professor Friesner and Physics I class with Professor Brooijmans at Columbia University if it weren't for all of CJ's help and guidance. He's perfect for any pre-med student because he has an in-depth understanding of multiple scientific disciplines. He can easily clarify and explain specific, complicated material (from organic chemistry to calculus to physics) and can help any pre-med student "connect the dots" across the many science-based classes they will be taking. He helped me to develop a deeper understanding of the scientific field as a whole, and was always encouraging and accommodating. I highly recommend giving CJ a call!"
