Can you recommend a book with UML and BPMN exercises?

There is a prob­lem with this because there is little lit­er­at­ure of this type and it is often paid sci­entif­ic pub­lic­a­tions. This is because 1. com­mer­cial pro­jects are pro­tec­ted by com­pany secrecy, 2. writ­ing such exer­cises and examples is labour intens­ive and few people do it. I can recom­mend books with examples and my blog where I always provide the lit­er­at­ure used and recom­men­ded under the posts: GO TO MY BLOG.
