I have had the ASA UAS Remote Pilot Test Prep book for a while and have gone through it many times. I am curious how well this book prepares you for the actual part 107 FAA exam. The book mentions that apparently the actual question pool used for the actual exam is private the the questions in the book are not exactly the questions from the exam. I don't know if the actual exam questions change over time or not. SO, I am wondering whether being proficient in this exam book will equate to being prepared for the exam. Thanks.
