Certification exam prep.
Free, forever.
Roughly 40% of an electrical certification is passing theory and code exams. FreeTradeCamp is a practice-and-guidance course for exactly that: study units mapped to each certificate, drill the math, then sit timed practice exams until the real one feels familiar.
Curriculum
Units mapped one-to-one to the three certificates — DC/AC Theory & Safety, Residential Wiring, Commercial & Industrial — each closing with an instant-feedback quiz and an "exam focus" brief.
Open the syllabusExam Center
Per-certificate exam guides (format, pass mark, study strategy) and timed, shuffled practice exams scored with a unit-by-unit breakdown telling you exactly what to restudy.
Sit a practice examFormula Lab
Four step-by-step solvers — Ohm's Law, voltage drop, series/parallel resistance, and conduit offset bends. See the work, not just the answer.
Open the labWiring Sandbox
A live schematic bench. Wire it dead, energize it, then operate the switches and watch current animate along the actual path — with voltage at every terminal and real-time hazard callouts when something is live that shouldn't be.
Open the benchReview Queue
Every question you miss — in a unit quiz or a practice exam — is queued automatically, hardest first, and only retires once you answer it correctly.
Drill your missesProgress & Badges
Unit clears, best exam scores, and sandbox circuits — tracked in your browser with a badge wall from Theory Cleared to Bench Certified. No account required.
