I just finished prep work on my Euclidean Geometry course. This involved rewriting or rebuilding lots of fiddly little things, so even though it was the “easy” one with minimal changes, it still took a whole day to do. (8-10 hours?) You can find the course web page here:
That has everything. All of the assignments are written. Even the exams are written, but I am not going to post those publicly. If you want to skip to the core of things, you can just look at the new syllabus and maybe the first assignment page.
I am feeling super cool, now, so I chose to decorate this post with a different version of Count Vertigo.
