I have looked into getting a Private Cert over the past 2 years. The only thing I can not get a strait answer on is what all tests they run on the Class III medical. Just trying to self evaluate before I waste the money seeing a AME or schooling.
No need to worry. If you're just getting a Class 3, then they'll check your vision and color perception, make sure you aren't deaf, check your blood pressure (which has very liberal standards in your favor) and might give you a drug test if he's in the mood. Basicly make sure you're not about to keel over.
