Pass the FE Electrical and Computer exam — even if it has been years since you last opened a textbook. Nodal covers all 17 NCEES knowledge areas with lessons written for engineers coming back to the material after a long break: the intuition first, then the formula, then a worked example, then how to recognise it on exam day. WHAT'S INSIDE • 529 original exam-style questions — multiple choice, select-all and numeric entry • Every question explained: the steps, the concept being tested, the trap that catches people, and why each wrong answer is tempting • 103 lessons across all 17 areas, with worked examples throughout • 17 formula sheets covering 456 equations, rendered properly rather than as flat images • Full-length timed exams on the real blueprint: 110 questions, 5 hours 20 minutes, the NCEES section distribution — plus half-length, 25-question and per-section exams • Adaptive practice that weights questions toward your weakest, heaviest-scoring areas • Spaced repetition that brings back everything you get wrong until it sticks • A readiness score that estimates your real exam result, weighted by how many questions each area actually carries • A daily plan, streaks, bookmarks and your own notes on any question BUILT FOR PEOPLE WITH JOBS Study in ten-minute gaps or three-hour blocks. Everything works offline — the entire question bank ships inside the app, so it runs on a plane, on the subway, or in a basement lab with no signal. FREE, PERMANENTLY All 103 lessons, all 17 formula sheets, 85 questions across every knowledge area, and the 25-question mini exam are free forever. No trial, no countdown. Full access is one payment that unlocks the remaining questions and every timed exam. It is not a subscription — nothing renews, and future questions are included. ACCURACY Every question was written and then independently re-solved by a second reviewer, with each numeric answer recomputed from scratch.
