I use Mr Gelston's one room school house- he is a live math teacher and I think he has patched some holes we had and my son is doing great. Ai love his vocabulary and positive attitude. Going from Singapore into something else has been a challenge. My son has finished 6th grade, and half of 7th in about 20 online line classes. You can get an assessment and a break for the first class to see if your a fit too. I am happy. My son just took the AMC 8 and did top 25% of 8th graders he is 11 years old.
