How long to review for the Mechanical Engineering (ME) 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 Mechanical Engineering (ME) Board Exam, the Mechanical Engineers Licensure Examination. No ME review center I found publishes its program length, so this estimate comes from PRC's exam calendar and the subject weights. 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 ME 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 ME board exam coverage. 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 ME exam is held in February and August. Here are the last two:
| Exam dates | Filing window |
|---|---|
| February 11 to 13, 2026 | November 13, 2025 to January 12, 2026 |
| August 7 to 9, 2026 | May 8 to July 8, 2026 |
So the next sitting is usually about 6 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 |
|---|---|---|
| Power Plant Engineering | 35% | 100 |
| Mathematics | 35% | 100 |
| Machine Design, Materials and Shop Practice | 30% | 100 |
To pass, you need a 70% average, with no subject below 50% (RA 8495). 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 7 | Power Plant Engineering: learn, then practice questions (35%) |
| 8 to 13 | Mathematics: learn, then practice questions (35%) |
| 14 to 18 | Machine Design, Materials and Shop Practice: learn, then practice questions (30%) |
| 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 ME 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 ME 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 February and August, based on PRC's 2025 and 2026 schedules.
