I just passed my Extra Class test this week and scored 50/50. I went to the same VE's for each test and after the Extra exam and some handshakes, they had questions about how I studied. I showed them my copy of your Extra class book, highlighted, notes written in the margins and so on. I used your books for each exam and they definitely made a difference for me. I did my part as well but your books definitely made it easier. The books are now part of the ham radio reference section in my library. I don't normally go out of my way to thank an author, in fact, I've never done this before but your books made such a big difference for me I felt I should reach out and let you know about it. So, thanks again for writing this series, 73! "
