The Electronics Engineering (ECE) board exam, officially the Electronics Engineers Licensure Examination, has four subjects of 100 items each: Mathematics, GEAS, Electronics Engineering, and Electronics Systems and Technologies. PRC's Table of Specifications says exactly how many items each topic gets. This post lays all of that out, so you can see where the points are before you plan your review.
Where this coverage comes from: Everything here comes from PRC's own documents, not from forum posts. The subjects, weights, and item counts are from the Board of Electronics Engineering's Enhanced Table of Specifications (Board Resolution No. 10, s. 2022), which applies from the October 2022 exam onward. The schedule is from PRC's program for the October 2026 exam. I checked all of it in November 2026.
A Table of Specifications (TOS) is the blueprint the Board writes questions from. Questions must stay within its scope, so it's the closest thing to an official syllabus.
As of the October 17 and 18, 2026 exam:
| Detail | What PRC says |
|---|---|
| Subjects | 4 |
| Items per subject | 100 (multiple choice) |
| Day 1 | Mathematics (8:00 AM to 12:00 NN), Electronics Engineering (1:00 to 6:00 PM) |
| Day 2 | GEAS (8:00 AM to 12:00 NN), Electronics Systems and Technologies (1:00 to 6:00 PM) |
| Calculators | One non-programmable calculator from PRC's approved list. Programmable models are banned. |
| To pass | 70% in each subject (RA 9292) |
| Subject | Weight | Items |
|---|---|---|
| Mathematics | 20% | 100 |
| General Engineering and Applied Sciences (GEAS) | 20% | 100 |
| Electronics Engineering | 30% | 100 |
| Electronics Systems and Technologies (EST) | 30% | 100 |
Some topics are split across subjects. For example, Electromagnetics appears in both Mathematics and Electronics Engineering. Feedback and Control Systems shows up in both too. So studying them once pays off twice.
| Topic | Items |
|---|---|
| Differential Calculus | 15 |
| Integral Calculus | 15 |
| Differential Equations | 15 |
| Advanced Engineering Mathematics for ECE | 15 |
| Engineering Data Analysis | 15 |
| Electromagnetics (vector analysis side) | 9 |
| Signals, Spectra and Signal Processing | 8 |
| Feedback and Control Systems | 8 |
| Topic | Items |
|---|---|
| Physics for Engineers | 15 |
| Chemistry for Engineers | 10 |
| Technopreneurship 101 | 10 |
| Physics 2 | 10 |
| Computer Programming | 10 |
| Environmental Science and Engineering | 10 |
| ECE Laws, Contracts, Ethics, Standards and Safety | 10 |
| Engineering Management | 9 |
| Materials Science and Engineering | 8 |
| Engineering Economics | 6 |
| CAD | 2 |
GEAS is wide. Physics alone is 25 items across two topics:
The laws topic covers obligations and contracts, the ECE pledge and CSC guidelines, how PRC regulates the profession, and related statutes like the Philippine Electrical Code.
GEAS has its own breakdown, down to the subtopic, in GEAS coverage in the ECE board exam.
| Topic | Items |
|---|---|
| Electronic Devices and Circuits | 14 |
| Electronic Circuit Analysis and Design | 14 |
| DC Electrical Circuits | 12 |
| AC Electrical Circuits | 12 |
| Logic Circuits and Switching Theory | 12 |
| Microprocessor and Microcontroller Systems and Design | 12 |
| Electromagnetics | 8 |
| Electronic Systems and Design | 8 |
| Feedback and Control Systems | 8 |
This is the most even subject. No topic is above 14 items, so you can't skip any of them.
| Topic | Items |
|---|---|
| Principles of Communications | 25 |
| Transmission and Antenna Systems | 23 |
| Data Communications | 20 |
| Digital Communications | 15 |
| Signals, Spectra and Signal Processing | 10 |
| Electronics 3: Electronic Systems and Design | 7 |
EST is mostly communications. Principles of Communications, Transmission and Antennas, and Data Communications together make up 68 of the 100 items.
Under RA 9292, you need 70% in each subject, not just a 70% average. There's one safety net. If you pass most subjects but score between 60% and 69% in the rest, you can take one removal exam for those subjects. Fail the removal exam and you fail the whole exam.
Here's what that means in practice. Say you get 75% in Math, 78% in GEAS, 72% in Electronics, and 65% in EST. You passed three of four, and your EST is above 60%, so you can take a removal exam in EST only. If your EST were 55%, the removal option wouldn't apply.
If you don't pass, the retake rules are in what happens if you fail the board exam. Recent results are in board exam passing rates.
Because every subject needs 70% on its own, your weakest subject matters more than your strongest. I'd take a quick diagnostic in each subject first, then put most of your hours into whichever one is lowest.
If EST is your weak spot, start with Principles of Communications and Transmission and Antennas. They're 48 items between them. If it's GEAS, start with the two physics topics.
Four: Mathematics (20%), General Engineering and Applied Sciences or GEAS (20%), Electronics Engineering (30%), and Electronics Systems and Technologies (30%). Each has 100 multiple-choice items.
400 in total, 100 per subject, based on PRC's Table of Specifications.
70% in each subject under RA 9292. If you pass most subjects and score 60% to 69% in the others, you can take one removal exam in those subjects.
Physics, chemistry, engineering economics and management, technopreneurship, materials science, computer programming, environmental science, ECE laws and ethics, and a little CAD.
Yes, one non-programmable calculator from PRC's approved list (Commission Resolution No. 1809, s. 2024). Programmable calculators are prohibited.
