My son took an official ACT test right before the Mathtopia ACT fall course and we were not happy with his Math score at all. I was in search of a good ACT prep course and came across Mathopia thru a friend. The course began in September and ended in December. Right before the last lesson was another ACT official test which my son registered for. We received the test results yesterday. The Math instructor, Mr. Kirikci is amazing. Looking at the way he connects with the kids and teaches the materials, I already knew what's coming. My son's Math ACT score went up from 19 to 26. Strongly recommend.
