Since some of you have come across useful links/videos that might help others in the class, I thought I would create a post where we can share helpful links.

So: if you have come across a link that you’ve found useful for our course (e.g., a YouTube video, a KhanAcademy quiz, etc), please post useful links as comments to this post (please include also a 1-sentence description of the content of the link and/or why you found it useful!)

(See my first comment below for an example.)

Note: each link you post at any point before the end of the semester will count as 1 participation point toward the Participation component of your course grade.
