I also got my approval on 11/20/2018 and still waiting for the prometric authorization. Do you guys know how much time they take to send out those authorizations?
NikR, keep us posted if you get you prometric authorization.
My guess would be getting 52-56 questions correct out of 80 for Civil Structural exam. People post failing scores and I have not seen anything greater than 51 for the Civil structural exam.
