I did mine at All ATP in Riverside, CA back in '98. Two tests, FE written and ATP. Two flights (split with another student -- we were both MIL), one with IP for practice and one with examiner. Never flew a piston twin before. It wasn't rocket science. If you're presently flying fighters then be prepared for slow motion -- I do not see how you can **** it up, despite previous comments advocating for buying extra time.
