Hubby held this certification for years, but let it lapse since he was no longer flying. He purchased this review manuel when his work implemented a new pay ladder for having his CEN which meant he needed to re-take the exam 🙄 Book has barely been cracked open, is not written in or highlighted and he did not utilize the online content, so this book WILL come with your code to register for the practice exams. He passed! And I'm sure you will too! 😉 Good luck! Smoke free; pet free home Ask about Closet Clear Out every Friday and Sunday for discounted shipping! NO POSHMARK ACCOUNT? NO PROBLEM!
