Watch 3–5 minute concept shorts before your sprint, dive deep with full topic walkthroughs, or join the Mentor Room for live Q&A with PE-licensed engineers.
Watch these before your sprint to prime the concepts. Each video is 3–5 minutes and covers exactly one testable topic.
Master Kirchhoff's Voltage and Current Laws with a worked three-loop example. The fastest way to set up any circuit problem on the PE exam.
Visual breakdown of line vs. phase relationships in balanced Delta and Wye configurations. Includes the √3 factor and when to apply it.
Why the per-unit system exists, how to choose a base, and how to convert between bases. The most common source of calculation errors on the PE exam.
NFPA 70E arc flash boundary calculations: Limited Approach, Restricted Approach, and Arc Flash Boundary. Exactly what the PE exam tests.
Positive, negative, and zero sequence components for unbalanced fault analysis. Includes the a-operator and how to set up sequence networks.
Key NEC Article 110 requirements tested on the PE exam: working space clearances, dedicated equipment space, and conductor sizing rules.
Join live weekly sessions with PE-licensed power engineers. Ask questions about concepts you're stuck on, get exam strategy advice, and hear how working engineers approach the same problems you'll see on test day.
Watch a concept short → Run a 15-min sprint on that topic → Review AI diagnosis → Repeat. This loop is proven to close knowledge gaps 3x faster than passive reading.
