What is the better reference material Mansour or EET? I heard for the Transportation Depth the book from Mansour is good and the other reference materials like the Green Book or HCM is not needed. Also, I heard good things about the EET Binder and that it covers all the Transportation Depth. I hear that both materials are detailed and either material will be more than enough for the exam. Can anyone confirm this? what is better Mansour or EET?
