if you are quoting from someone, you must always credit them.

If I am quoting Washington's farewell address I cite G. Washington not some history book that copied out the farewell address, unless there is some significant variation in versions that is important to history.

And, if I am concerned about the meaning of "is" I cite the Oxford English Dictionary, not Bill Clinton who raised it's meaning as an epistemological issue.

You must have had this perspective while you were in school.

I doubt your grades were legitimate if you did all your work this way. Heck, you probably got homeworks from prior year students and turned them in as yours and credited it as yours because you were the one who wrote it on your pieces of paper. It was original then, wasn’t it?

You are showing extremely poor judgement.
