Was I wrong.....?

Been thinking about ir this whole week. I knew the Organic report was supposed to be handed in on Friday but I told my class that it is due on Thursday late afternoon. I knew that if I said it is due on Friday, many people will take their own sweet time in handing in. The teacher said specifically she wants it at 10 on Friday which is right after our MicroBiology Lecture. I had no choice but to do that...
