Be sure you get copies of all the texts that material can come from as possible, because there will be all kinds of questions. For instance, get the AASHTO manual because there will be a lot of bridge questions and the NDS specification for wood. I found "Bridge Design for the Civil and Structural PE" and "Timber Design for C&S PE", both by Kim to be very useful. Also, "Reinforced Concrete" by Nawy is a lifesaver. I didn't have a prestressed book but it would have been useful. Hope this helps.
