Agree with @skieurope. Especially as the author, you often read what you expect to see rather than what is actually there. This is another reason not to leave essays till the last minute - a couple of days’ break from writing and then proofreading again will also often make it easier to spot errors.
And yeah, Rick is better than Duke. Just about every school info session we went to said they’d seen a cut and paste essay that had left another school’s name in it somewhere…
