does anyone know how many questions are in the suitefoundation exam? and how many questions needed to pass?

Passing score is not revealed by NetSuite but you need to clear all the sections of the exam to pass it.

I believe they say how many questions it is and how long you have when you register for it. IIRC it's 80 questions and 2 hours. As NickSuite said, they just say whether you failed or passed and don't reveal the percentage needed to pass.
