I just purchased "An Elementary Introduction to the Wolfram Language" and would like to use the automatically graded exercises referenced in the book at wolfr.am/eiwl However, I get stuck clicking the "go to free course" button on this page https://www.wolfram.com/wolfram-u/an-elementary-introduction-to-the-wolfram-language/ and get nowhere. Is there still an actual graded exercise course online or not? Anxious to get started.
Thanks if anyone can help.
Automatic grading is within the online book: https://www.wolfram.com/language/elementary-introduction/2nd-ed/
Click on any chapter, at the end, you can find what you need:
It is not in the MOOC on WolframU
