re: PPI review course for PE exam

The morning questions (water,geotechnical, etc) are pretty basic and not very in depth. I was in the same shoes as you, mainly doing structural work and hardly any civil work. I just did all the problems and sample tests I coukd to review the morning material. The CERM is your best friend for that portion of the exam. I found most of the answers to those questions could be found right out of that manual. The afternoon part (structural) was a little more difficult and the questions were more in depth. Good luck!
