Our experience of Mathacademy so far: son (8th grade) has completed Integrated Math 1,2, & 3 and started Mathacademy AP Calculus BC last week. He is a hardworking kid (doing a multi-year Chemistry Olympiad training course and insists on getting there 1/2 hour early so that he always gets “his seat” — middle of front row, right in front of Chinese teacher. Teacher’s students populate at least 3/4 of the US Olympiad team every year—it’s hard core training. So that’s the student in question’s attitude towards academics. Anyway, he’s scoring 780-800 more recently on SAT practice tests (old, new on Bluebook, College Panda.) He’ll take the genuine SAT in May and another in June—-I’ll post outcome. As of now, I’m relatively confident that Mathacademy has taught him pretty well so far. He loves Mathacademy and as of now we plan to continue with it over the next 4 years.
