Unlike ECE where all 4 subjects are equal, REE weighs Electrical Engineering Professional Subjects at half the entire exam. AC/DC circuits, electrical machines, and power systems must receive the largest share of your review time. A strong Day 2 performance is non-negotiable.

PEC questions appear throughout Day 2. You cannot memorize the entire code, but knowing the structure and the most commonly tested articles — grounding, wiring methods, branch circuits, services, and motors — is achievable and highly rewarded under timed conditions. Start PEC in your first month of review.

Transformer efficiency, voltage regulation, equivalent circuit parameters, and motor torque-speed relationships are consistently tested with multi-step calculations. Under exam pressure, the only way to solve these confidently within the time limit is to have practiced them so many times the steps become reflexive.

Many REE examinees misread the rules and assume scoring 50% in Mathematics is acceptable as long as their average is high. It is not — a score below 50% in any subject disqualifies you entirely, even with a 95% in EE Professional Subjects. Every subject must be passed.

More than half of those who sat for the April 2026 REE exam passed. This is significantly higher than ECE (44.85%). Candidates who review systematically with past board questions and focus heavily on Day 2 subjects consistently outperform those who study without a structured plan.
