Thank you! I spoke to Matthew Blackwood today and he said when they gave the 30 minute guideline in the FAQ, it was back when they only offered Pre-Algebra. He indicated he would remove that. So for the higher level maths it would be more. He said Algebra 1 would be more like 45-90 minutes. He also felt the course was one step below AoPS in rigor/intensity but higher than comparable programs out there. I'm planning to give it a shot beginning Aug 17 and see how it goes. I'm very excited to have it at less than private school price and relatively hands off for me. As an FYI, he called me within 5-10 minutes after filling out the online question submission form.
