Latest revision as of 00:51, 15 February 2017

These resources are pulled together from various online sources. I've tried to be as specific as possible to the problems in the pre-lecture assignments. However, many related videos can be found by the same authors as those posted below. If you find other videos (or other resources) that you found particularly useful, let me know.

Please send me requests for more suitable supplements when these do not prove sufficient.

Pre-lecture assignment link
