Quote From Skig:
I need some help!! A friend of mine just realised they've plagiarised by accident. Their work is original but they found a few sentences that have been added to their lit review chapter word by word. Not sure if that makes a difference but it's referenced.

Realistically I believe it's highly unlikely anyone will know but they're worried as they still have their viva to come. Any ideas what I can advise them?

My gut feeling says deny any knowledge IF anyone brings it up at the viva...

Any other ideas/thoughts?
