A practice question with the wrong answer key teaches you the wrong thing. Here is how we check the answer keys in our ASVAB app, and how to tell us when one looks wrong.
1. A second, blind pass on every key
The app has 948 questions. For the 900 text questions, a separate pass answered every one again without seeing the key, and we compared the two. Where they disagreed, or the wording read two ways, we went back to the question and made a ruling. In the October 2026 check, the two passes agreed on 899 of 900. We looked again at 4 questions: 2 keys stood as written and 2 got clearer wording (listed below). No key changed.
On 2026-10-27 we drew a fresh sample of 50 questions across the subtests and answered them blind again. All 50 matched the key. A sample is not a guarantee, so the report button stays on every question.
2. Math recomputed by a script
The 200 Arithmetic Reasoning and Mathematics Knowledge questions each carry the math behind the answer. A script reworks every one from the numbers in the question and flags any result that does not match the key. In October 2026 all 200 matched. The 48 Assembling Objects drawings are built by a script that checks the keyed figure is the one whose pieces fit; all 48 passed when we reran it in October 2026.
The practice questions on our study pages went through the same two steps before they were published.
3. Report any question from the app
Every question in the app has a report button: a flag at the top of the question, and a line under the explanation. Pick what looks wrong (wrong answer, confusing, typo, or other), add a note if you like, and the app opens an email to support@sdvsignal.com with the question number filled in. Nothing is sent unless you send it.
4. Questions we have fixed
When we change a question because of a check or a report, it goes here with the date. Newest first.
| Date | Question | What changed |
|---|---|---|
| 2026-10-20 | #7051 (Auto Information) | One choice used wording from older engines with a distributor. It now reads "Spark timing too far advanced", and the explanation names low-octane fuel and computer (knock sensor) timing. The right answer did not change. |
| 2026-10-20 | #8047 (Shop Information) | The question said a chisel with a wooden or plastic handle should be struck with a mallet, which is too broad: a chisel with a steel striking cap can take a hammer. It now says "a wooden handle and no steel striking cap". The right answer did not change. |
Questions people ask
Are the answers in the app ever wrong?
They can be. Every key has had a second, separate check, but people and scripts both miss things. That is why every question has a report button, and why this page lists every question we have fixed.
What happens when I report a question?
The app opens an email to support@sdvsignal.com with the question number and the keyed answer filled in. You choose whether to send it. We recheck every reported question, and if it changes, it goes on the list on this page with the date.
Are these real ASVAB questions?
No. Every question in the app was written for SDV Signal to match the official subtest descriptions. Real ASVAB items are not public.
