Why the frown? Don't be uneasy about it.
Besides testout and previous knowledge, what all have you done to study? Have you done as many practice tests as you can with 90+ scores? Have you spent LOTS of time on a simulator or gear? Have you read the whole book untill you are comfortable with every word? Watched the CCNA prep videos? Read over the cisco whitepapers on the main topics? Remember all your commands?
This should be a part of your check list and I hope you didn't totally rely on testout. Testout is good, but not that good. Anyways good luck with it!
