LabVIEW is all about an unfair advantage!
THe requirement to re-certify is in-place to ensure you are up-to-date on LV.
I used the SDE on one of my exams ( I think?).
If you can exploit the SC and complete the coding in the time allocated, I would be suprised if they did not allow it.
That being said, please keep in mind that I don't know the official NI stand on this subject and you should really contact NI Traning to find out if the allow it and if the center where you will be taking the test will have it installed on the machine you will be using.
