Aswath Damodaran is one of the key professors teaching valuation. I highly appreciate his approach to knowledge sharing, making his excel spreadsheets, writings and datasets available for free through is resource page at NY Stern University.
Damodaran has now gone a step further making his Valuation Course available online including homework assignments, powerpoints etc. through Symynd.
For people just starting out in valuations or seeking to refresh their memories please consider following this course. For valuation professionals, perhaps tune in later for special topics.
