I wouldn't worry too much Pabloscopy. Coming out of the exam it seems many were stumped with that final question, I'd say only the upper level students will get it.
I found most of the exam pretty typical for a physics exam. Maybe some of the multiple choice were slightly harder, and that final question with the graph probably threw people because there were two springs, rather than the typical one spring setup. A few very predictable linear acceleration/projectile questions. They used particle collisions to assess momentum conservation rather than vehicles, a nice question from an algebraic position (cancelling out the mass of the particles). No real tension questions. The loop vehicle question unexpectedly didn't assess minimum velocity but instead gave velocity at the top of the loop, making it an energy question. Relativity was pretty minor in this exam, I can only really recall a length dilation in multiple choice. Usual electricity transmission question, though perhaps a slight increase on comprehension and reasoning versus calculations.
