I took civil/structural as well. I also took EET's prep course for just the morning breadth since they didn't have one for structural depth. After taking EET's course, I think that 30-32 of the morning problems were doable/reasonable with EET's training. However the last 8 of those were for me the hydraulics questions, and they were killer. There was also one problem that was structural which I also thought they didn't give enough information on. EET never went over a problem like it without giving more information.
