Hello all! Looked through a bunch of threads but couldn't find anything about commercial oral exam. I know I need to study the POH and the commercial oral exam guide as well as how a constant speed prop and landing gear system work. But I wanted to know if there was anything else I should be studying to get ready for the oral exam that I will probably take in a couple of months? Thanks for the help!

AC 120-12A should make it about as clear as mud for you. At least you will have a referece. Good luck!
