How it's similar: - focused on mastery - good treatment of math How it's different: - doesn't cover elementary school topics - lessons are text, not video - paid, not free - lessons are presented based on what you already know (e.g. you can't choose to study a topic before you've demonstrated mastery of all topics it depends on) - I pick the next lesson from a very small set (usually 5 options, sometimes fewer), so there's no wasting time choosing what to study next - really great spaced repetition system that prevents forgetting |
