Can I create quizzes and assessments with iTunesU course manager?

I have this question too. Having looked at the support documentation it seems that you can't directly create assessments in Course Manager, but the iBooks Author tool has a simple MCQ question tool that allows you to create review questions which you could link to to from within a course page, or post. The question marks aren't recorded however within iBooks, so can't be used by an instructor as a reference on how well their students are doing.
