Near brain meltdown

This past weekend I took the first 4 hour session of a practice exam for the PE exam I am taking on Friday (yikes thats really close). Problem #1 was easy and confidence boosting. Problem #2 was slighly more obscure but the answer was obtainable. Problem #3 had me sweating and frantically paging through all my books. Talk about demoralizing. Maybe I think they ought to make the practice exams really easy so I could have a false sense of security and at least sleep in peaceful ignorant bliss for the next few nights.
