PE Civil Breadth & Water Resources and Environmental Depth

The PE Civil exam is eight hours long and divided into two sections: breadth and depth. The breadth portion takes place in the morning and is made up of questions from all areas of civil engineering. The depth portion takes place in the afternoon and focuses on one specific area of civil engineering that is selected by the examinee.

Course Features

Our PE Civil exam review courses consist of comprehensive lectures and practice sessions to ensure our students have an excellent understanding of the material. Each review course follows the official NCEES exam specifications and is divided into two parts: The first part includes 48 hours of breadth review, which covers the topics of the breadth portion of exam. The second part includes 48 hours of discipline-specific review, which covers the student’s chosen depth subject. Student registration also includes access to our Study Hub at no additional cost.
