Thanks so much! Great advice! 5 hours and 40 minutes....is going to be torture. LOL! I appreciate knowing others had their 2015 books in September, and I'd prefer to take the book that I've been using all along for familiarity. If, on the bad luck chance I have to retake, I'll wait til 2017 and purchase those then. Also, I did find that list of approved manuals, and 2015 is fine, although at an "obvious disadvantage". I've even found some of the new codes and changes on line and have been adding those into my book. Think it's going to be ok!
