FE Civil vs FE Mechanical: Which Exam Should You Take?

The Decision in 30 Seconds

Did you study civil engineering? Take FE Civil. Did you study mechanical engineering? Take FE Mechanical. Done.

If you're still reading, you're probably in one of the edge cases: a general or engineering technology degree, or coursework that split across both disciplines. Let's sort that out.

What Each Exam Actually Covers

The FE Civil has 14 knowledge areas. Its heaviest topics, at 10–15 questions each, are Water Resources and Environmental Engineering, Structural Engineering, and Geotechnical Engineering; Transportation Engineering follows at 9–14, then Mathematics and Statistics, Statics, and Construction Engineering at 8–12 each. If you took courses in hydrology, geotech, transportation, and structural analysis, that's your exam.

The FE Mechanical has 14 knowledge areas. Its heaviest topics, at 10–15 questions each, are Dynamics, Fluid Mechanics, Thermodynamics, and Mechanical Design and Analysis; Statics and Mechanics of Materials follow at 9–14 each, then Heat Transfer and Materials at 7–11 each. If you took thermodynamics, heat transfer, machine design, and vibrations, that's your exam.

The overlap between the two exams is smaller than people assume. Both test Mathematics, Statics, Mechanics of Materials, Fluid Mechanics, and Engineering Economics. But the Civil exam adds surveying, geotech, water resources, transportation, structural design, and construction, topics a mechanical engineering student likely never studied. The Mechanical exam adds thermodynamics at a much deeper level, heat transfer, mechanical design, measurements and controls, and electricity and magnetism, topics a civil engineering student likely never studied.

Edge Cases

"I have a general engineering degree."

Look at your transcript. Count the courses that align with each exam's topic list. If you took more civil-adjacent courses (structures, geotech, hydrology, transportation), take Civil. If you took more mechanical-adjacent courses (thermo, heat transfer, machine design, dynamics), take Mechanical. If it's genuinely 50/50, take whichever discipline you plan to practice in, since the EIT credential and eventual PE will be in that discipline.

"I have an engineering technology degree."

Same logic. Match your coursework to the exam topics. Engineering technology programs sometimes have a more applied focus that aligns well with specific FE topics. Check your state board's eligibility requirements. Some states have different experience requirements for ET graduates.

"I heard FE Mechanical has a higher pass rate."

It does, historically slightly higher than Civil. But this likely reflects the candidate pool, not inherent difficulty. Mechanical engineering programs tend to map very tightly to the exam specification, which means ME graduates are well-prepared by default. Taking Mechanical when your background is Civil to chase a modest pass rate difference, while simultaneously losing familiarity with half the exam topics, is bad math.

"I'm years out of school and don't remember either discipline."

Take the exam in your degree discipline anyway. Relearning material you once knew is significantly faster than learning it for the first time. Your coursework built neural pathways that reactivate during review, even if they feel dormant. Mechanical engineers re-learning thermodynamics get up to speed faster than they would learn geotechnical engineering from scratch.
