WELCOME TO MATHEXCEL
Math Tutoring Service (in-person or online) in Saint Louis, Missouri
Mr. Yalcin (Mr. Y), your holistic expert math teacher.
Hello :)
I established mathexcel.org, a private math tutoring service. I have been an educator since 1996 and taught in several countries (The US, Turkiye, Republic of Georgia, and Kyrgyzstan). I have total 18 years of teaching experience; 10 years college teaching and 8 years secondary school teaching. I taught students from 6th grade to college seniors. I have been living and working in the US since 2005. I am a certified math teacher for grades 5th through 12th in the states of Missouri and Arizona. I also completed modern classroom project teaching certification in 2024. I also hold the certification in University Teaching Skills from Saint Louis University, which I got in 2010. I am here to help people having troubles with mastering mathematics, statistics, and becoming an effective self-learner.
