I have passed the IFR written and am halfway through the IFR training. Since I am in book mode, have the King commercial home study and can get an online endorsement to take the commercial written now, is there any reason I cannot/should not do it? I know the commercial certificate can be limited to VFR if you do not have the IFR rating. But is the commercial written I would pass before getting the IFR applicable to getting an unrestricted commercial certificate if I take the practical after getting the IFR? I know this is not the normal path, but just curious. I like the idea of getting the book work out of the way, and having the knowledge during the actual flight training. Thanks.
