How long to review for the Electrical Engineering (REE) 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 Electrical Engineering (REE) Board Exam, the Registered Electrical Engineers Licensure Examination. No REE review center I found publishes its program length. But Excel Review Center was already enrolling for the 2027 exams in November 2026, about 5 months before an 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 REE 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 REE 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 REE exam is held in April, and August or September. Here are the last two:
| Exam dates | Filing window |
|---|---|
| April 21 and 22, 2026 | January 21 to March 23, 2026 |
| September 5 and 6, 2026 | June 5 to August 6, 2026 |
So the next sitting is usually about 4 to 5 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 |
|---|---|
| Electrical Engineering Professional Subjects | 45% |
| Engineering Sciences and Allied Subjects | 30% |
| Mathematics | 25% |
To pass, you need a 70% weighted average, with no subject below 50% (RA 7920). 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 9 | Electrical Engineering Professional Subjects: learn, then practice questions (45%) |
| 10 to 14 | Engineering Sciences and Allied Subjects: learn, then practice questions (30%) |
| 15 to 18 | Mathematics: learn, then practice questions (25%) |
| 19 to 20 | Two full timed mock exams, then your weakest topics only |
Two habits run through every week:
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 REE exam fails you if any subject is below 50%, even with a good average.
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 REE 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 April, and August or September, based on PRC's 2025 and 2026 schedules.
