In Modern History if the quote is relevant to build the argument and you said something like 'an historian said' there wouldn't be a problem because we do expect you to use ideas from historians and understand that exam stress can lead you to forget the actual historian's name.

That being said last year a number of students were penalised for plagiarism in the English exam. I believe the issue was that they used ideas from a story in the creative writing section and the markers recognised the story and penalised them accordingly.
