I stopped flying in 2011 back in College. I had passed my commercial written back then but never did my commercial check ride (don't ask k thankz) Anyways I started flying again back in March 2018, have since bought a plane and logged 50-60 hours. I want to get finally get my commercial rating and then probably CFI so I always have 1 hour more than my friend who finally got his PPL + Instrument this year (he also bought a plane) and he is encroaching on my total time of 280. Which commercial ground should I take to retake the exam... also do I have to get another endorsement/sign off from a different instructor to take the written again? I live no where near where I went to college. Also- anyone ever do their commercial in a Mooney?
