exams and solutions will remain in a private repository and will be available upon request.  This both archives the course materials and provides a platform for easy dissemination.  Based on our experience with this semester's edition, we will expand the pre-test to include problems on statistics and astronomical coordinate systems. ``foundational'' topics in astronomy, such as the inverse square law flux.  These pre-test questions are asked again on the final to provide a measurement of the student gain. gain (eq.~\ref{eqn:gain}).
