Use this NPPE calculator to estimate your weighted overall result after you receive your topic-by-topic percentages.
This tool gives an approximate NPPE result based on typical topic weights. It is for guidance only and does not replace your association’s official pass/fail outcome.
Who Should Use This Calculator?
This calculator is designed for engineers‑in‑training who wrote the 110‑question multiple choice NPPE format and received category percentages for Topics I–VI. It is especially useful if you:
- Want to understand how close you were to the 65% pass mark, or
- Are planning a rewrite and want to see how much each topic affects your overall score.
Why Use an NPPE Results Calculator?
Most associations do not report your numerical NPPE score — you simply receive a pass/fail result. This leaves many candidates wondering “Did I just barely pass?” or “How close was I?”
You also cannot simply average your six topic scores, because each topic is weighted differently. Topics II, III, and IV contain more questions than the others, so they contribute more to your final result.
How to Use the Calculator
- Locate your category results from your association’s notification letter or online portal.
- Adjust each slider in the calculator to match the percentage you received for every NPPE syllabus topic.
- Review your estimated weighted overall score and compare it with the 65% pass threshold.
Passing mark: 65% overall (equated)
You do not need to pass each individual topic — only your weighted overall score matters.
You do not need to pass each individual topic — only your weighted overall score matters.
You don't need to pass each syllabus topic to pass the NPPE. You only need to achieve at least 65% overall on the weighted exam result. However, Topics II, III, and IV together account for most of the marks, so candidates who fail usually struggle in one or more of those sections. If you are retaking the exam, focus your study time there first.
