What the numbers say

  • Water Resources and Environmental is the largest PE Civil depth by first-time takers and has the highest first-time pass rate.
  • Repeat takers pass at 38% to 49% across the depths, well below first-time takers.
  • NCEES shows these rates for the January to June or July to December population of each year-round exam and updates them each July and January.

  • Take the free diagnostic: 12 questions, one from each knowledge area, scored by area.
  • Fix the area it picks with its lesson, then try four fresh questions on it.
  • Sit the full 80-question mock in two 4-hour halves before you book.

Try 4 questions

Question 1Uniform flow and Manning's equation
A concrete-lined rectangular channel is 10.0 ft wide and flows at a uniform depth of 3.0 ft on a slope of 0.002 ft/ft. Manning's n is 0.015. Using Manning's equation in US units (constant 1.49), the discharge is most nearly:
Question 2Wells and drawdown
A production well has a static water level 85 ft below the ground surface. After pumping at 420 gpm long enough for the level to stabilize, the pumping water level is 117 ft below the surface. The specific capacity of the well is most nearly:
Question 3Sedimentation
A rectangular sedimentation basin is 120 ft long, 30 ft wide and 12 ft deep and treats 2.0 MGD. The surface overflow rate is most nearly:
Question 4Engineering economics and life-cycle cost
A levee costs $2,400,000 to build and $35,000 a year to maintain. It reduces expected flood damage by $260,000 a year. Over a 30-year life at 5%, (P/A, 5%, 30) = 15.3725. Define B/C = (present worth of benefits) / (first cost + present worth of maintenance). The B/C ratio is most nearly:
