Math & Physics Professor. Ph.D. in Theoretical Physics from the University of Florida. Over 15 years of teaching experience. AP Physics Reader for years.

Dr. Wang’s lessons were genuinely the only reason I got a 5 on AP Calculus BC. He is so helpful and dedicated to his students and always makes sure that they fully understand all of the concepts covered. Sometimes it felt as if he was able to literally read my mind when I didn’t understand something and explain it in ways that allowed for me to understand. He made sure that I stayed on track and had enough material to practice off of. I am so so grateful for all of his help! Highly recommend :)

If you are looking for a top-tier math or physics tutor, look no further than Changlong. He helped my daughter turn her AP Physics grade around completely, leading her to an A. He is reliable, highly knowledgeable, and knows exactly how to build a student's confidence. His teaching methods work, and the results speak for themselves. Five stars

Dr. Wang was my professor for 2 academic semesters in 11th grade dual enrollment. He is so talented when it comes to the explanation of the most complex mathematical concepts. He actually gets down to the level of the students and helps them understand in fun and engaging ways. I remember when I was struggling with understanding how Gauss-Jordan and Gaussian elimination work, but as soon as I went to him, he explained everything in a way that stuck with me and showed me how to do it on my calculator in case I'm wrestling against time. I really recommend!

Dr. Wang is my Pre-Calculus professor at Broward College, and he does an incredible job with teaching.

He is a great professor for my pre calculus class!

Dr. Wang is the best math teacher I’ve ever had. I took him for my trigonometry credit and as someone who is not strong in math, he was a great help. He is very patient, organized, and kind. He prepares helpful study materials that I used to do well on tests and quizzes. If I had any questions he would break it down in a way I could easily understand. He is skilled in multiple different types of math and can definitely help anyone who needs it.

Professor Wang is excellent at what he does with a grand depth of knowledge as well as experience. His explanations are clear and understandable. He is super open to answering any questions or further explaining any confusion.

Dr. Wang is a great math tutor and professor! His teaching method is super easy to follow and understand. Dr. Wang shows multiple ways and techniques that are best for you to arrive at the same answer and he will make sure you understand the concept! I definitely recommend to anyone looking for lessons or tutoring! Thank you Dr. Wang!!

He was my math professor for 2 semesters. He is pretty chill but good at explaining the concepts. If you don't understand, he'll go back and explain it over and over again. He also constantly asks for feedback to reflect on his teaching for his students. Most of the students he has that I know got a 700+ on the SAT.

Dr. Wang is an incredible, patience, and attentive tutor. He turned hard concepts into easily digestible content for me. He encouraged and gave me the tools to explore different ways of approaching math problems.

He is incredibly sweet, and I would absolutely recommend him to anyone who may be in need of a tutor!

Changlong is an extremely talented instructor. He is very good at breaking down concepts, even the most complicated ones. Anything you are struggling with, he can explain it in a way you understand. Very knowledgeable in his field, and I am honored to be his student.

I was briefly taught Calculus by him, and I left the class feeling driven and excited to learn more! He makes it extremely easy to visualize more complex formats in a way that makes it far more absorbable.
