Being that we'd all be just be guessing, I'll take a stab at it:
- Tab your references, so you can quickly find the tables and such that you use to design
- Make sure you KNOW where things are in the books you take with you. Test day is not the time for "it's here, somewhere!"
- Read and then work through a scenario for loading, carrying loads to the ground. With a day devoted to gravity, this skill if critical.
- Be sure you can work through problems and document the steps you took, as you would in your calcs - this is what is being graded.
- Using the editions required for the exams (one version behind current in most cases - check the NCEES website), learn how to compute wind loads using the methods in ASCE 7.
- Even if you usually spread the loads, round up, and approximate for real work, be sure you can apply the code-required methods.
- Get to know the codes and be able to design with materials you don't typically use; the exams cover concrete, steel, wood, and masonry, and you have to pass for all materials presented on the exam.
Now that we all rely on software, hand calcs on the main structure are usually either just a check or are for rough approximations. Know moment distribution, stiffness of continuous frames, force distribution with rigid and flexible diaphragms.
And with the increased emphasis on seismic, refresh yourself on chord forces, drag struts, and lateral-force resisting systems. Also, look over requirements for foundation elements under earthquake loading.
