To be a bit more thorough...
Maybe it is just too generous with the score after giving hints. At the higher levels, I seem to need spoonfeeding with hints, and struggle to see how to apply the ideas in my own games.
Eg: Hint - white's goal here is an eventual e4. OK I wouldn't have guessed that. Why is white's goal e4 anyway? Why is control of d5 and f5, say, more important today than some other objective? (It's thematic - does that mean just take my word for it?) Don't I want to understand this before working out how to prepare e4?
One last thing. In tactics trainer there is space for comments under each problem - but often there is not much to say about the tactics problems. In chess mentor there is often a lot to say about a position, but nowhere for comments.
Using adaptive mode gives me lessons at around 2200-2300. I think I learn more from those around 1800-2000.
So an adaptive-but-easier setting would be good.
