i've heard rumors but no official word that the detroit FSDO has a 80% fail rate. the instructor i'm working with says they decide if you pass before you get there to fill there quota for failures. i don't know if this is true but the ride is tough. my instructor said if you fail, they will reschedule you for 3-4 days. this isn't enough time to learn all of the stuff you failed on and they know that. they just can't pass everyone. i'm working on my initial cfi now and its hard not to get discouraged by this info. i figure if i study hard and know as much as i can i at least gave it my best shot. hey, at least with the FSDO they don't charge you to take 'em.
