Results at test scores don't mean the programme is a failure - I'd bet a lot of those kids couldn't care less about the class and only did the minimum of work required to pass. There's also the issue of diminishing returns - if you need to spend one hour to get a 75/100 grade but need to spend 3 hours more just to get 80/100 it won't be worth the effort for a lot of kids - it sure wouldn't have been for me.
