Expert to make people learn far faster than normally possible. Spanish, Portuguese too. Can speak 10+ languages. Can learn to speak new languages faster than anyone you know.

I am surprised to hear that D.C. is tutoring again. He is more than a tutor. I know he used to change the global STEM education, especially for math and physics to the next levels far beyond what we are at currently. His main focus used to be collaborating directly at the governmental levels. Obviously he hasn't been lucky with the governments. I remember that he had the invited meeting with 4-5 ministers or vice-ministers of Guatemala several years ago. He was not a small fish. Sadly he got betrayed by all the bosses in the country. I saw his intense fights and struggles. I was convinced that he was for something super powerful and impactful at that time.

I happened to get to know him during his struggles to uplift the math education with the Ministry of Education in Guatemala. I watched 3 of his national TV interviews some years ago. Then I got to know him better. I don't think that he will do tutoring very long as he has far more ambitious projects and still pushing. Whoever can learn math or physics or whatever he offers here with D.C., I will consider that as very lucky opportunities. Learn math or physics or chemistry or whatever from him. I bet your life will see the new light, not just improve your grades or test scores.

Just relax and let him guide you. For him to pump your grades will be a piece of cake. Just go with the flow with him.

Good luck with your endeavour.

D.C. is one of a kind. Whatever he does, he seems to do extremely fast. I have seen him tutoring the university students with Statistics, Math, and Physics a few years ago. Within very short time, the magic seemed to happen always. I know he is extremely talented in whatever he does: math, physics, piano improvisations, speaking foreign languages at a speed that is absolutely not possible. Why am I saying this? When he tutors, he doesn't just tutor the subject. For him, it seems to be like improvisations of his piano music. So spontaneous, fresh, and powerful. Keep on inspiring with your help, man.

D.C. is someone who is very special, I must say. It was about 9-10 years ago. He helped my son who had the SAT math 640 about 7-10 days before the test. Lee had made him a top students for his AP Physics before, but I didn't expect my son to advance from 640 to the perfect 800 within a week after Lee taught him SAT math for about 5 sessions each of which lasted for about 2 hours if I remember correctly. By the third session or so, my son was getting the straight perfect math scores in SAT already.
He had helped both my son and daughter with math and physics so much, making them even the best students of their entire schools, which had never happened to them before. So I'm very very grateful to D.C.
Thank you, D.C.

I met Mr. Lee about 13-15 years ago in Queens, NY. From a referal, Lee helped my son for math mostly and then chemistry. My son had struggled for many years with math when he was about 10th grade. He was one of the worst few math students in his classes for at least 5 years. Then Mr. Lee started tutoring twice a week. He told me that he could have make my son improve his math even faster, but he himself needed some steady income at that time. So he told me that he would make my son rise to the top perhaps in 4-6 months instead of a few weeks or less. I didn't believe him at that time. In 4-5-6 months after Lee started teaching my son, my son became the best math students in his class, which really shocked me. That really happened as he had predicted to me before. Eventually after about half a year, our relationship ended and I haven't seen him ever since then.
Due to the personal problems, I am no longer in NYC area and returned to South Korea for my personal business, but I wish for the best to Mr. Lee. He was always friendly and light-spirited for us. At times, he put a bit of pressures to my son, but never very much. About the right amount of pressures and challenges so that my son could reach the target. From South Korea, I salute.
So, whoever become a student of Mr. Lee, I think you should consider yourself lucky. Fighting, Mr. Lee!
