I am teaching an independent-reading course from Simon's "Representations of finite and compact groups". I chose this book based on fond memories from a previous reading course in which I had participated as assistant, but then discovered that it has no exercises. At least for the early material, I'm not finding it easy to create relevant exercises myself.

Is it appropriate to ask if anyone has references to books, or online resources for other courses, that would have relevant exercises? This isn't exactly a research-level mathematics question, but I have seen other questions here on course organisation (though maybe more about appropriate content than this kind of nitty-gritty detail).
