> "adaptive diagnostic assessment..." but this didn't work very well for me.

I found it a bit controversial too, but it makes sense if you consider the goals of MA / creator's approach. MA aims for "you're going to learn to mastery, passing 100% or you don't know the subject yet". Which works great if that's what you're after, and less well if you want to just get to know the landscape and be more comfortable appling a few things every few months. (One of the reasons I dropped out was when it made me do way too many vector/matrix multiplications that felt like busy work I'm never going to do manually, but it would make sense at uni time) You can trigger the diagnostic again btw if you think something's seriously off.
