How this course was organized
What's here, and what isn't
- MIT's own materials here did not support a verified, course-wide order, so they are grouped by section instead.
Not included here
1 item from the source could not be safely included:
- MIT's page format for this item wasn't recognized clearly enough to place it safely.
Materials by section
Grouped by section, as MIT organized them. Not sequenced or ordered.
