On this URL I found a feature I´m very much interested in:
There are questions placed in the text; by clicking on a link the answers are added to the readable text.
Now this seems to me a nice possibility to pose questions for an excercise without having to handle the a bit heavygoing lesson module.
Since the specified course is downloadable, I´ve tried it on my 1.9.4+-site.
But: The feature does not work: question and and answers are shown from the start.
