Gleim 2019 Instrument Pilot FAA Knowledge Test
Not for Helicopter
My mistake for not researching this book. It does not cover Helicopter.
I have passed FAA written exams with extremely high scores by using these low-tech and inexpensive books. Especially useful are the explanations right next to the questions on the same page. Simply cover the answers to make an honest attempt and then see if the answer is right, and right for the correct reasons. If incorrect mark it so it is covered in review. Explanations Gleim gives for the incorrect responses is also very helpful. I have received perfect scores using this product and method.
