About Lesson
This course section was recently updated!
All the lectures AFTER this lecture are the old course lectures that were published before the update. All lectures BEFORE this lecture are the new lectures.
The old lectures are kept around temporarily to allow existing students to finish this section (i.e., if they started before the new lectures were released).
If you watched all the lectures up to this point you can therefore ignore the remaining lectures in this course section and continue with the next section instead.
