Org should be ideal for this.  Each subtree can be configured with its
own export settings, so e.g. you can use a different LaTeX style for the
lecture slides, exams, and problem sets.

Don't forget also that you can measure student progress in this file,
too :) Org has a spreadsheet, and you could use it as a grade book if
you wish.
