I'm loving the content I have explored so far, but I am having some trouble with general navigation here.  For example, I am very interested in AI right now, but my colleagues hate it.  I thought that if I worked through the How I Learned to Stop Worrying and Love AI course, I would be able to have better discussions with them.  So I watched the course video, then accididentally clicked Mark Complete, before having the change to go through the workbook.  I cannot for the life of my find that workbook or switch my status from Complete to In Progress.  Thanks for any help you can offer.
