I may be lost here. You have a proficiency return in 3 parts? I know that some places allow a 'short form' return, which many (including myself) disagree with being an option. But 3 separate returns of the same work that most all of us had to do in one sitting? Please say this isn't so. That's just too easy.
I did it in one. Also did my FC in one and will complete the MM proficiency in one as well.
