I took the Structural exam and have to agree that the morning portion was surprisingly difficult. I ended up running out of time and had to flat out guess on 4 or 5 of them. I was misled by the relative ease of the NCEES practice exam. I thought they asked questions in weird ways and I had several problems where I could eliminate 2 answers but then could see either of the remaining 2 as being partially right and/or wrong! I felt confident about all the structural questions, give or take a couple, since it's my background. Maybe I did just enough though..we shall see! Good luck to all!
