REE (Registered Electrical Engineer) is the full professional license for electrical engineers, covering power systems, electronics, machines, and all EE disciplines. RME (Registered Master Electrician) is a vocational license focused on electrical installation and wiring. REE requires a BS Electrical Engineering degree, while RME requires vocational training. REE has broader scope of practice including design and consultancy work.
How many times is the REE exam given per year?
The REE board exam is conducted twice a year (biannually) by the PRC. Typical schedules are in April and August. For 2025, the scheduled dates are April 17-18 and August 18-19. Always check the official PRC website for the most updated schedule and deadlines for application.
What are the best review centers for the EE board exam?
Popular review centers for REE include Excel Review Center, MERIT Review Center, CRAM Review, and Infinity Review. However, the "best" center depends on your learning style and location. Consider factors like instructor quality, success rate, schedule flexibility, and cost. Many successful examinees also self-review using online resources like PinoyReviewer.com, reference books, and practice tests.
What are the commonly difficult topics in the REE exam?
Based on examinees' feedback, the most challenging topics include: Advanced Engineering Mathematics (differential equations, Laplace transforms), Power System Protection and Relay Coordination,Control Systems (transfer functions, stability analysis), Philippine Electrical Code (specific articles and tables), and Illumination Design Calculations. Focus extra study time on these areas and practice many problems.
How should I review for PEC questions?
For the Philippine Electrical Code: (1) Get the latest PEC edition and read Chapters 2, 3, and 4 thoroughly. (2) Memorize key tables like conductor ampacity, wire sizes, and protection requirements. (3) Practice scenario-based questions about code violations. (4) Understand the rationale behind each code requirement, not just memorize. (5) Review grounding, GFCI/AFCI requirements, and load calculations extensively.
What are the career opportunities after passing the REE exam?
After becoming a Registered Electrical Engineer, you can work as: Power Systems Engineerin generation/transmission/distribution companies, Design Engineer for electrical systems in buildings and facilities, Project Engineer for construction and infrastructure,Consulting Engineer offering electrical design services, Plant/Maintenance Engineerin manufacturing, Sales/Application Engineer for electrical equipment suppliers, or pursue government positions in agencies like DOE, NEA, or DPWH. Many REEs also start their own electrical contracting businesses.
