There was one school that asked to explain any breaks in university enrollment. Well I took a year off and was really active in research so I talk about that in my SoP. The question asked to explain any breaks, which I did thoroughly in my SoP. I just copied and pasted the part from my SoP where I talk about it and add a line or two of context before it. I didn't even think about it. Looking back I should have thought about it.
Did I do a bad thing? Will this come off as lazy? The passage stands on its own, IMO.
