I've been studying from the book Noncommutative Rings by Herstein (not as a part of some official course), but unfortunately it doesn't contain any exercises apart from a few simple ones in the body. I was wondering if anyone had any suggestions on where I could find suitable exercises (since from what I've seen, this material is covered quite differently in different books, so it may not necessarily be possible to just take any other book on noncommutative algebra and use its exercises).
Any help will be appreciated.
