<p>I feel for you, IceQube.I always research things like that beforehand but fortunately have never had the exact same prompt as online. However, I would definitely find it hard not to use the ideas of a great essay I read, I’d probably just include them subconsciously.
At the same time, I think you should have to redo it because it technically was plagiarism if you didn’t cite it and used the ideas. I think it wasn’t really your fault though because you were simply trying to prepare for an essay.</p>
