How long to review for the Electronics Engineering (ECE) board exam: 4 to 5 months, based on PRC's calendar and subject weights, with a 20-week plan.

Plan on 4 to 5 months of full-time review for the Electronics Engineering (ECE) Board Exam, the Electronics Engineers Licensure Examination. No ECE review center I found publishes its program length. But Excel Review Center was already enrolling for the 2027 exams in November 2026, about 4 to 5 months before a March or April exam, and that fits PRC's calendar. This post shows where that number comes from and gives you a 20-week plan, as of November 2026.
After reading this, you can pick a start date for your ECE review and split your weeks by subject.
The exam dates and filing windows come from PRC's 2025 and 2026 schedules. The subjects and weights come from PRC's own documents, which I laid out in ECE board exam coverage. Review program dates come from the providers' own sites. I checked all of them on November 9, 2026.
There's no official answer to how long you should review. Treat this as a starting plan and adjust it after your first diagnostic test.
The ECE exam is held in March or April, and October. Here are the last two:
| Exam dates | Filing window |
|---|---|
| March 17 and 18, 2026 | December 17, 2025 to February 16, 2026 |
| October 17 and 18, 2026 | July 17 to September 17, 2026 |
So the next sitting is usually about 6 to 7 months away. That's your maximum review window if you're deciding between two dates.
Filing on LERIS opened about 3 months before each exam and closed about 1 month before. So start reviewing before the window opens, not when you file. PRC hasn't released its 2027 dates yet; the expected months are in the PRC board exam schedule.
| Subject | Weight | Items |
|---|---|---|
| Electronics Engineering | 30% | 100 |
| Electronics Systems and Technologies (EST) | 30% | 100 |
| Mathematics | 20% | 100 |
| General Engineering and Applied Sciences (GEAS) | 20% | 100 |
To pass, you need 70% in each of the four subjects (RA 9292). The weights tell you where your weeks should go.
The plan splits the middle weeks by subject weight. Heavier subjects get more weeks.
| Weeks | Focus |
|---|---|
| 1 | Timed diagnostic: one practice set per subject. Note your weakest topics. |
| 2 to 6 | Electronics Engineering: learn, then practice questions (30%) |
| 7 to 11 | Electronics Systems and Technologies (EST): learn, then practice questions (30%) |
| 12 to 15 | Mathematics: learn, then practice questions (20%) |
| 16 to 18 | General Engineering and Applied Sciences (GEAS): learn, then practice questions (20%) |
| 19 to 20 | Two full timed mock exams, then your weakest topics only |
Two habits run through every week:
One ECE-specific change: since every subject needs 70%, use your week 1 diagnostic to reorder the subjects. Start with your weakest one, not the heaviest.
Cut weeks from subjects your diagnostic says you're already strong in. Don't cut the heaviest subject just because it's long.
And don't drop any subject. The ECE exam needs 70% in every one of them.
If you're working full-time, you'll need more weeks, not fewer. See how to review for the board exam while working full-time. If you're retaking, start from your subject ratings instead of week 1: see a retake review plan.
4 to 5 months of full-time review is a sensible target for the ECE exam. Pick your sitting, count back 20 weeks, and start before the filing window opens.
About 4 to 5 months of full-time review is a common target, based on PRC's calendar and the subject weights. Working reviewees need more.
Count back from your exam date. Filing opens about 3 months before the exam, so start reviewing at least a month or two before the filing window opens.
Twice a year, in March or April, and October, based on PRC's 2025 and 2026 schedules.
