Howdy,
The survey is there as part of a wicked plot to ensure you get the hardest possible test based on your current level...
JUST KIDDING
The survey is part of an ongoing process to keep making sure that people who *should* pass, do, and that people who *should not* pass, do not. It does not affect your question set in any way.
The survey is used in a statistical analysis, compared with the individual questions, and they are looking for things like, "this person did not know ANYTHING about threads, but got every thread question correct." Or, this person claims to be expert at threads, but missed every question."
Of course, we have no way of knowing whether or not people are telling the truth in the survey, but it still helps overall. It is MOST important during the beta, because sometimes a question might appear and we discover that the most knowledgeable people interpret it in a more subtle way, and thus get it wrong, while the more beginning person gets it right, and that's the kind of question that would the be thrown out of the exam during the beta process.
So, it really helps if you are as honest as possible in the survey, and your answers will have NO affect on your actual exam questions.
Some day, we may switch to the "adaptive" format, but that is down the road, and you'll know if and when it happens!
have fun,
Kathy
