Well that's the main problem. People are going to in these exams, needing certain grades to get into UNI, parents expectations, yourself wanting to achieve of course and then you go into exams and around exam time, it gets "panick time" from personal experience, you are revising everything, hoping the paper comes up with the questions you want. People setting up accomodation for Uni, now just needing the grades, it's borderline whether they get in, I don't think it's so suprising that most (in my opinion) would look at questions unless as you say, they are super confident and prepared.
Anyway, I am running a poll on this on the Student Room, currently 4-1 (to yes they would look) http://www.thestudentroom.co.uk/showthread.php?t=1331526
Edit: 7-1.
I presume you also wouldn't mind if a few hundred people got to see the paper early by mistake, cheated and got better grades than you causing you to miss out on a uni place?
