I took 640-801 Exam this morning and failed

; I got 792; I got 56 questions; and I was only able to attempt 49 questions; I got 6-8 Simulations; I got RIP, OSPF, Frame Relay, Access List, Network Troubleshooting Simulations;
Another thing the Exam Center had very slow PCs (Pentium-II); I know that the exam doesnot count the time, when it loads the Simulation; But when I was typing the commands on Router, it was very very slow;
I have a question; When we start the exam, it asks about your experience with different topics e.g LAN, WAN, Access Lists, Routing etc.; It was having different options e.g. No experience, Good working experience; (However its not a part of exam), But does your exam depend on these selections; I selected "Good Working Experience" for all topics;
Please let me know, if it makes a difference or not.
