Thank you to everyone who reports issues
Every question in our bank has been written and reviewed carefully, but with thousands of problems spanning a dozen engineering disciplines, errors happen. When a user takes the time to work through a problem, verify the math, and send us a detailed report — that’s a genuine contribution to the quality of the question bank for every future test-taker. We read every report, verify every claim independently, and push fixes as quickly as possible. This page is our public record of confirmed corrections.
How to Report an Issue
If you believe a question has a wrong answer, a calculation error, or misleading wording, please contact us with:
- The Question ID (shown in the app when you review a question)
- A brief description of what you believe is wrong
- Your working, if you have it — even a rough sketch helps
We aim to respond and verify within 48 hours. If your report checks out, we will update the question bank and credit the correction here.
Confirmed Corrections
| Date | Exam | Topic | Description | Status |
|---|---|---|---|---|
| May 3, 2026 | PE Civil WRE | Hydraulic Grade Line & EGL (Q40063) | The calculator steps field was incorrectly copied from a different question (pipe pressure class sizing) and bore no relation to the HGL/EGL problem. The EGL answer option was also corrected from 324.4 ft to 324.2 ft to reflect the exact computation (HGL = 323.846 ft; EGL = 323.846 + 0.388 = 324.234 ft). The explanation was updated to explicitly call out the psi → psf unit conversion (45 × 144 / 62.4). Reported by Joshua P. | Fixed |
| Apr 27, 2026 | PE Civil WRE | Open Channel Hydraulics | Answer key error in a channel-contraction specific-energy question. The explanation was also updated to correctly describe the direction of depth change in subcritical flow through a contraction. Reported by Joshua P. | Fixed |
