DISAPPOINTED.....

Got the 847 again,
Design = 100%
Implementation = 63%
Troubleshooting = 53%
Technology = 78%
Surprsisnigly, I was able to answer the questions quickly and easily enough that I had 25 minutes remaining for the last 5 questions !!!
The " regret " word at the end was a SUPER shock as I was able to confidently answer most questions. I cant even figure where to improve on, as I dont know where I went wrong...
There were no questions on Frame Relay, just one each on ACls, VTP and NAT. All other questions were from STP and Routing Protocols.
Any advice now please...
