Books and courses on graphic design

Hello! I’m looking to expand my design knowledge and thinking of getting a new course or a book. I’d like an advanced course but could not find any apart from fundamentals. If I’d get a book, maybe something that is visual reference heavy. The expense is not a problem, I really need a refresh! Thanks in advance!
