Craigrut and Xiao Hu,

Yes! We've actually had our HSK team compiling answers for existing questions for the last few months now. The system is actually setup (if you click on the red/green button you'll see the question you got right or wrong, ideally with an explanation of why it was incorrect).

So this is a data issue. We need to review the explanations -- many of which I believe are in Chinese at the upper levels -- and then get them imported into the system. I expect that we'll have this implemented in the next two weeks.

Best,

--david
