“When I started college, I had to take a calculus class after having taken a 13-year break from school, and Chang helped me not only on successfully completing that class, but encouraged me along the way when it got frustrating.”

— College Student, Champaign IL

 

“Chang explains concepts very well. He breaks down problems and makes them easy to understand. He is very clear, patient, and encouraging. I highly recommend him.”

— College Student, Champaign IL

 

“He was always excited to teach and I knew that he truly loves his job and the subject he teaches. He also took his time and made sure I understood the material. The lessons are definitely worth it.”

— High School Student, Urbana IL

 

“Not only is Chang a great teacher, but he is also a great friend. He has a good sense of humor and even though it was like a math class, it didn’t feel like it at all. I highly recommend Chang’s services. Add Sum Solutions is the way to go!”

— Middle School Student, Urbana IL

 

“Even to this day, he continues to keep in touch with his past students providing them with advice on college and answering any questions they may have as they progress through high school and college. I am truly grateful for all the work he has done over these past years.”

— Adult Education Student, Urbana IL

“Chang has tutored my son for several years now and I am extremely happy with his work ethic, mathematics teaching philosophy, and ability to coordinate with our family's schedule and communication needs.”

— Middle School Parent, Champaign IL

 

“There are plenty of individuals that understand math but very few that can teach it and Chang is undoubtedly one of those people. He not only explains concepts in ways students can thoroughly understand but also allows them to take control of their own learning experience.”

— High School Parent, Urbana IL

 

“Education can be as challenging as being an adult. Making the process of learning fun and entertaining is what keeps any human interested. The fact that Chang can make that happen is a miracle.”

— Middle School Parent, Champaign IL

 

“Chang's math teaching philosophy is very progressive with modern pedagogy research, where abstract concepts like math should be taught incorporating different areas of the brain such as incorporating movement and games into some sessions, and relating those lessons to real world topics that the student is interested in.”

— Middle School Parent, Champaign IL

 

“Chang is loved by his students and shares a superior relationship that I can confidently say no other tutor in town has with their students. In this way, he is not only a teacher but a friend who inspires confidence and comfort through his words, a quality that has proven to ensure a greater success than simply understanding the material alone.”

— Middle School Parent, Urbana IL
