We started at Lv 3 but you might want to start Lv 4 and see. I noticed when we moved up (fairly quickly) that a lot was repeated in Lv 4 and DD8 (just turned) got credit for a lot in Lv 4 as well. One thing to know is that it will give him an assessment when you start and the website tells you (not sure where I read this) if they score above 90% on the initial assessment to move them up. But even it's above 70-80% it will go pretty quickly. I think we started Lv 3 at maybe 60-70% range and finished the first level pretty quickly only doing maybe 15-20 min 3-4 days/week.
