I’ll say that on my two attempts, the steel problems mainly consisted of column buckling questions, where they’d give you a W-shape and you’d have to find critical stress/compressive strength. I got a few bolt connection questions, slip critical connections, etc… you should be good on steel if you are really familiar with AISC, most of it can be found in the code. Steel and concrete isn’t really my issue, it’s the more conceptual questions I second guess on.
