I thought I'd jump in while Matt's away on vacation. Yes, Matt did incorporate questions from Google's official practice exam in the course exam, as stated up front in the exam description. We have a refresh on the course planned for the next quarter. In the meantime, you might want to review this Google doc, a compilation of changes to the exam that other exam takers have reported so far.
Plus you have all the good luck vibes coming to you from all of us at Linux Academy! I'm sure you'll do great!
