Chat: [Study Group] Syllabus


Recommended Posts

I've been working on a rough syllabus for what I'd like to discuss in the study group. Deciding how to order the topics has been pretty tricky. It is very likely that we'll all decide to change the ordering around as we begin our discussions. I may also try to merge some topics into a single session. But we need to start somewhere.

Please let me know if you have any suggestions or if you notice any missing topics that you'd like to discuss.
