The Fundamentals of Engineering (FE) Electrical and Computer Engineering exam is a critical milestone for aspiring professional engineers. Whether you recently graduated or are years into your career, passing the FE exam is the first formal step toward earning your Professional Engineer (PE) license. This guide breaks down everything you need to know—from what the exam covers to exactly how to study for it.
What Is the FE Exam and Why Does It Matter?
Administered by the National Council of Examiners for Engineering and Surveying (NCEES), the FE exam is a computer-based test designed to assess whether you have the foundational knowledge expected of an entry-level engineer. It consists of 110 questions answered over a 5 hour and 20 minute session, and it is offered year-round at Pearson VUE testing centers.
Passing the FE exam earns you the designation of Engineer Intern (EI) or Engineer in Training (EIT), depending on your state. From there, after accumulating the required years of professional experience (typically four years under a licensed PE), you become eligible to sit for the PE exam and earn full licensure.
Career Benefits of Passing the FE Exam
- PE licensure pathway: A PE license is legally required to sign and seal engineering drawings, offer services directly to the public, and hold certain senior engineering positions.
- Competitive advantage: Even before you earn your PE, the EIT credential signals competence and commitment to employers.
- Higher earning potential: Licensed professional engineers consistently earn higher salaries than their unlicensed peers, with many surveys showing a 10–20% premium.
- Career mobility: Licensure is recognized across all 50 U.S. states and territories through comity agreements, making it easier to work in different jurisdictions.
Complete Breakdown of All 17 Topic Areas
The FE Electrical and Computer Engineering exam draws from 17 distinct knowledge areas. NCEES publishes an exam specification that assigns each topic a percentage range, which translates to an approximate number of questions out of 110. Below is each topic area with its estimated question count and what to expect.
1. Mathematics (6–9 questions)
Covers analytic geometry, calculus, differential equations, linear algebra, complex numbers, and discrete mathematics. You will need to solve integrals, work with matrices, and apply Euler's formula. The NCEES FE Reference Handbook includes key formulas, but you need to know how to apply them quickly.
2. Probability and Statistics (4–6 questions)
Expect questions on probability distributions (normal, binomial, Poisson), measures of central tendency, regression analysis, hypothesis testing, and expected values. Many of these problems are straightforward if you understand the underlying distributions.
3. Ethics and Professional Practice (3–5 questions)
Covers the NCEES Model Rules of Professional Conduct, ethical obligations, public safety considerations, and licensure requirements. These are conceptual rather than computational—read the ethics section in the reference handbook carefully, as it is essentially free points.
4. Engineering Economics (3–5 questions)
Topics include time value of money, present and future worth analysis, annual cost comparisons, benefit-cost analysis, rate of return, and depreciation. Master the standard factor formulas (P/F, F/P, A/P, etc.) and you will handle these efficiently.
5. Properties of Electrical Materials (3–5 questions)
Focuses on conductivity, resistivity, dielectric properties, magnetic permeability, and semiconductor physics. Understand the differences between conductors, insulators, and semiconductors, along with basic material behavior under varying conditions.
6. Engineering Sciences (4–6 questions)
A broad category covering work, energy, power, charge, forces, and basic mechanics relevant to electrical systems. Think of it as applied physics—conservation of energy, electrostatics, and basic thermodynamic concepts may all appear.
7. Circuit Analysis (8–12 questions)
One of the heaviest topics on the exam. Covers DC and AC circuit analysis, Kirchhoff's laws, Thevenin and Norton equivalents, node and mesh analysis, impedance, phasors, power factor, and transient response of RL, RC, and RLC circuits. This is a must-master category.
8. Linear Systems (5–8 questions)
Focuses on Laplace transforms, transfer functions, impulse and step responses, convolution, and system stability. Understanding how to move between time-domain and frequency-domain representations is essential.
9. Signal Processing (5–8 questions)
Covers Fourier series and transforms, sampling theory (Nyquist), discrete-time signals, z-transforms, and basic filter design (low-pass, high-pass, band-pass). Know Shannon's sampling theorem and how aliasing occurs.
10. Electronics (7–11 questions)
Another high-weight topic. Includes diode circuits, BJT and MOSFET analysis, amplifier configurations (common emitter, common source), operational amplifier circuits, biasing, and frequency response. You should be comfortable analyzing both ideal and non-ideal op-amp circuits.
11. Power Systems (8–12 questions)
Covers three-phase systems, power generation and transmission, transformers, per-unit analysis, power factor correction, fault analysis, and motor fundamentals. This is one of the most heavily tested areas—spend significant study time here.
12. Electromagnetics (5–8 questions)
Topics include electrostatics, magnetostatics, Maxwell's equations, electromagnetic wave propagation, transmission lines, and Smith charts. Focus on applying Gauss's law, Faraday's law, and understanding standing wave ratios.
13. Control Systems (6–9 questions)
Covers block diagrams, feedback systems, stability criteria (Routh-Hurwitz, Bode plots, Nyquist), root locus, PID controllers, and steady-state error analysis. Be comfortable interpreting Bode magnitude and phase plots.
14. Communications (5–8 questions)
Includes AM and FM modulation, noise, bandwidth, channel capacity (Shannon's theorem), digital modulation schemes, and basic information theory. Know how to calculate signal-to-noise ratio and channel capacity.
15. Computer Networks (3–5 questions)
Covers the OSI and TCP/IP models, routing, switching, network topologies, protocols, and basic network security concepts. These tend to be more conceptual and definition-based.
16. Digital Systems (7–11 questions)
Another major topic area. Covers Boolean algebra, logic gates, combinational and sequential circuits, flip-flops, counters, registers, state machines, and memory architectures. Practice simplifying logic expressions with Karnaugh maps and Boolean identities.
17. Computer Systems and Software Engineering (4–6 questions)
Covers computer architecture, instruction sets, memory hierarchies, operating system fundamentals, data structures, algorithms, and software development lifecycles. Understand concepts like pipelining, cache memory, stacks, queues, and big-O notation.
Which Topics Should You Prioritize?
Not all 17 topics carry equal weight. A strategic study plan focuses your limited time where it will earn the most points. The four highest-yield topics are:
- Circuit Analysis (8–12 questions) — the backbone of electrical engineering
- Power Systems (8–12 questions) — heavily tested and formula-driven
- Electronics (7–11 questions) — requires solid device-level understanding
- Digital Systems (7–11 questions) — high volume and very learnable
Together, these four topics account for roughly 30 to 46 questions—approximately 27% to 42% of the entire exam. If you can consistently answer these correctly, you are well on your way to passing.
After mastering those, move to the mid-weight topics: Control Systems, Linear Systems, Signal Processing, Communications, Electromagnetics, and Mathematics. These collectively represent another 35–40% of the exam.
Finally, review the lighter topics: Ethics, Engineering Economics, Probability and Statistics, Properties of Electrical Materials, Engineering Sciences, Computer Networks, and Computer Systems/Software Engineering. While they carry fewer questions individually, together they still account for roughly 20–30% of the exam—and many of these are among the easiest to pick up quickly.
