Realistic PE Practice Exams in a True Exam Simulator
Every PE practice exam runs in an online exam simulator that reproduces the actual computer-based NCEES exam: for PE Civil, the same 80-question length, the same 9-hour appointment, and every question type the real exam uses, from multiple choice and multiple-select to fill-in-the-blank, drag-and-drop, and point-and-click. Questions are solved with the NCEES PE Civil Reference Handbook and the design standards supplied in the exam, so the references you practice with are the ones you will search on exam day.
After each exam, a detailed score report breaks your performance down by knowledge area, so you always know which subject your next study hour belongs to, and you can retake every exam as many times as you like, in timed exam mode or in practice modes that show each solution as you go.
PE Civil Water Resources and Environmental Exam Prep
Our PE Civil Water Resources and Environmental Practice Exams give you full-length, 80-question exams built to the official NCEES specifications: all 12 knowledge areas, from closed-conduit and open-channel hydraulics and hydrology to drinking water and wastewater treatment and project sitework, each weighted like the actual exam. Questions include the channel and pipe drawings and data tables water questions depend on, every solution cites the exact PE Civil Reference Handbook section or design standard it came from, and it is available in two versions, one for exams before April 2027 and one for the April 2027 design-standards update.

About the Principles and Practice of Engineering (PE) Exam
The Principles and Practice of Engineering (PE) exam is the second of the two exams on the path to becoming a licensed Professional Engineer, after the FE exam. Most state licensing boards also require qualifying engineering experience before you sit for it, and our guide to PE exam requirements explains who can take it and when.
NCEES offers the PE in many disciplines. The PE Civil exam is 80 questions in a 9-hour appointment and comes in five depths: Construction, Geotechnical, Structural, Transportation, and Water Resources and Environmental. Our PE Civil exam guide compares them, and our PE Civil Water Resources and Environmental exam guide covers the depth with the most first-time takers in detail.
Wondering about your odds? See the current PE exam pass rates by discipline, and our honest look at how hard the PE exam really is.
Most candidates prepare over three to six months. Our guide to how to study for the PE exam lays out a study plan, and the PE exam cost breakdown covers registration fees and what your state licensing board charges.
Frequently Asked Questions About PE Exam Prep
Which PE Exam Should I Take?
Take the PE exam in the discipline you practice. For civil engineers, NCEES offers the PE Civil exam in five depths, so choose the depth that matches your daily work: a water engineer who sizes storm sewers and pump stations, for example, is best served by the Water Resources and Environmental depth.
What Is the Best Way to Study for the PE Exam?
Work through the NCEES specification for your exam area by area, study with the same references supplied in the exam, and finish with full-length, timed practice exams. Realistic practice exams show which knowledge areas still need work and build the reference navigation speed the long exam day demands.
How Long Should I Prepare for the PE Exam?
Most candidates plan three to six months of steady study, depending on how closely their daily work matches the exam specification. The knowledge areas outside your practice deserve the most time.
Is the PE Exam Hard to Pass?
It is demanding but passable with structured preparation. Per NCEES Squared 2025, 71% of first-time takers passed the PE Civil Water Resources and Environmental exam, so roughly three in ten did not. Candidates who practice under real exam conditions walk in knowing the format, the references, and their weak areas.
Is This Prep Aligned with the Current NCEES PE Exam Specifications?
Yes. Every practice exam follows the current official NCEES specifications for its exam, with question counts in each knowledge area mirroring the actual exam. Where NCEES changes the supplied design standards, as it does for PE Civil from April 2027, a separate version of the practice exams covers the updated list.
How Does the Money-Back Passing Guarantee Work?
If you complete our practice exams, pass the final test, and still fail your PE exam, we will issue you a 100% refund, with no access extensions, just your money back. See the Projectific Passing Guarantee page for full details.
Do I Need Anything Besides the NCEES PE Civil Reference Handbook?
Only the design standards NCEES supplies with the exam. Every question in our practice exams is solved with the NCEES PE Civil Reference Handbook and those design standards, exactly like the actual exam, where they are provided as searchable onscreen references. Practicing this way builds the navigation speed the timed exam demands.
How Long Can I Access the Practice Exams?
You will have unlimited access for one year, starting from the date of your purchase, with unlimited retakes of every exam.
