Zaskar, read the article!!
"mismatch between what they had been taught and the content of the questions they found on the exam paper."
There were no past papers because it was the first year that spec had been used, there were specimen papers but there is a pretty big difference between knowing the information and being able to write it down in the way the exam board wants you to.
Also, I'm in my second year at uni, its no different from college in the revision aspect, loads of past papers to look at its just youre required to do some more work off your own back.
