I am 100% with you HB.
Aerodynamics for me was an exercise in bewilderment. AFT book is nothing like the exam (almost). Although the information is mostly there, the questions in the exam were so oblique and offputting that I ended up screwing up the obvious. Maybe I'm just an idiot...
Definitely buy a different book.
There are questions in the exam that weren't in the textbooks, go figure.
