The two student helpers are false as #*"& and the same ones seem to crop up in different courses across the range - and even on the Hodder introduction in one case that I know of!
That said, if one rises above that dishonesty, they're great ways of learning the structure. Add Remember-its 2000+ vocablary software and I think a home-based student will be giving themselves the best shot at fluency.
