I Filled Out One Of Those Online Career Assessments With Fed-ex Kinko’s And…?

…I accidentally clicked the wrong bubble. It said something about “working well under stress.” I pressed “Strongly Disagree” when I meant to press “Neutral.”
Can I call these people to tell them I screwed up or should I just kiss this job good-bye?
Yes, in reality, I can’t stand to work under stress but I need this job.
BTW, this is a repost of an unanswered question.
