FE Environmental Exam Study Plan

A 12-week study plan for the FE Environmental exam built from the NCEES specification: 110 questions, 6 hours, 15 topic areas with question counts and a suggested split of study hours.

Fundamentals of Engineering (FE) exams · Last reviewed

This plan is built from the NCEES specification for the FE Environmental CBT exam. It gives the exam format, the topic areas with the number of questions NCEES assigns to each, a suggested split of 90 study hours, and a 12-week schedule. Exam formats and specifications are revised from time to time, so confirm everything on ncees.org before you register.

With 110 questions in 6 hours, the average is about 3.3 minutes per question, counting the tutorial and break time, so the time available per question is slightly less. Plan your pacing from that.

Topic areas and suggested study hours

The question ranges are copied from the NCEES specification. The share and the hours are this site's suggestion: each topic's share is the midpoint of its question range as a part of all midpoints, and the hours split 90 total hours in that proportion. They are a starting point. Move hours to the topics where your diagnostic score is lowest.

12-week schedule

  1. Week 1: read the NCEES specification and look at the reference handbook layout. Take a timed diagnostic from the practice exam and record your score for each topic area.
  2. Weeks 2 and 3: the heaviest topic areas first, Fluid Mechanics and Hydraulics and Water and Wastewater. Work problems by hand, then check the answers and the method.
  3. Weeks 4 and 5: Surface Water Resources and Hydrology and Groundwater, Soils, and Sediments.
  4. Weeks 6 to 8: the remaining areas (Air Quality and Control; Fundamental Principles; Environmental Chemistry; Solid and Hazardous Waste; Mathematics; Ethics and Professional Practice; and the rest). Lighter areas get a shorter pass.
  5. Week 9: a full-length timed practice set under exam conditions, with the reference material only.
  6. Week 10: review every missed question. For each, record whether the miss was a concept error, a calculation error or a handbook-lookup error. Do a second timed set.
  7. Week 11: close the gaps from the review. Do not start new material.
  8. Week 12: a light review, and the logistics: your appointment, identification, the testing-center rules and the route there.

How to use the practice questions

  • Attempt each question before you read the answer.
  • Time yourself at about 3.3 minutes per question or less on the timed sets.
  • Practice finding formulas in the electronic reference quickly. Lookup speed is part of the exam.
  • Keep an error log with three columns: concept, calculation and lookup.
  • The practice exams on this site are original study material. They are not NCEES questions and passing is not guaranteed.

Before you register

  • Eligibility, experience requirements and application steps are set by your state or territory licensing board. NCEES lists the boards on its website.
  • Open the NCEES specification linked below and check its effective date against the date you plan to test.
  • Check the NCEES site for the current FE exam fee and registration steps.
