I am a pilot who will be teaching a ground school to help dispatchers pass their written exam. I have looked over both the Gleim and ASA test prep books, and I am unsure which is the better resource. I'm aware of the different styles, I personally prefer the layout of the ASA books, but I'm finding in this case that the Gleim has much more detail. The two books are really different, which is leaving me unsure as to which one to use in the course. Has anyone taken the written recently, if so, which study book did you use and did you find it prepared you well? Is there anything like a "study buddy" app for the DXP that I can recommend to students? Thank you!
