Yes, I noticed that as well. Just to play Devil's Advocate for a bit: assume 12 hours of material each week (Maths/English lessons plus some homework tasks), and a 36 week school year. I'm assuming something like ages 11 to 16, so something like 2160 hours total. That is a fair amount to author before you have a contract is it not? (As a teacher myself, I would have suggested leading into the scheme with 10% of that with good quality interactive material broken into small enough topics so the teachers could integrate it with what they use already.)
