Submit a correction through the contact page
If you find an incorrect answer, an unclear question, an explanation that does not match the evidence, or a practice tool that behaves unexpectedly, please report it. A specific report helps us locate the exact item and check the reasoning instead of guessing which version you saw.
Submit a Correction on the Contact Page
Use the contact form’s page URL field for the page you are reporting. In the subject, write Correction — [page title] — [question number]. Put the details in the message. If the issue affects a study guide, simulator, or other resource rather than a numbered question, use its section heading or mission number instead.
You do not need to be certain that something is wrong before asking us to check it. Explain what you observed and why it seems inconsistent. Please distinguish the answer you selected from the answer the page marked correct; that difference is important when investigating scoring.
What to include in your report
- Exact page URL. Copy the address of the resource with the issue. A broad description such as “the subnet test” may refer to several pages.
- Item location. Include the difficulty level, question number, and a short identifying phrase from the prompt. For the pilot diagnostic, include the question number and unit. For a simulator, include the mission and the step where the problem occurs.
- What the page currently says or does. Identify the answer letter and wording, the disputed sentence, or the displayed score. Report the evidence as you saw it before proposing a fix.
- What you think should change. State your proposed answer or revised wording, and explain the mechanism or calculation supporting it. If two options appear correct, explain how each fits the stated conditions.
- Supporting evidence. Include a worked calculation, relevant command output with private details removed, or a link to an authoritative technical source. For exam-format facts, identify the official College Board page and the exam year.
- Reproduction details for a tool issue. Include your device, browser, selected level or filter, the answers or actions leading to the result, and what happened instead of what you expected.
Answer positions can differ between tests and difficulty levels. “Question 4 should be C” is difficult to verify without the page, level, and option wording. The strongest report identifies the item and shows the reasoning behind the correction.
Examples of useful correction reports
Addressing or subnet calculation
“On [page URL], Medium Question 7 gives a host at 192.168.40.70/27. The explanation places it in the .32–.63 block. A /27 has 32-address blocks, so .70 belongs to .64–.95. Please check the stated network and the resulting answer.”
This report identifies the exact calculation and shows the intermediate boundary. It does not rely only on a preferred answer letter.
Two defensible choices
“On [page URL], Question 12 asks for the next step after a TCP connection times out. Both the route check and the firewall-log check appear reasonable because the prompt does not give a working path control or a matching deny. Could the question provide another observation or make the requested priority clearer?”
This report explains why the evidence may be insufficient to separate the options. It asks for a clearer decision rather than treating every timeout as proof of one cause.
Score or interaction problem
“On [page URL], I selected [option wording] for Question 3. The feedback said ‘Correct,’ but Show My Score still showed zero correct after three answers. I used [browser and version] on [device], with [level or filter]. I can reproduce it by [steps].”
Include both the feedback and the score. Note whether you restarted, changed difficulty, or reloaded; those actions may intentionally start a new attempt.
Exam-year information
“On [page URL], the section labeled [heading] describes [format detail] for the 2027 pilot. The official College Board page at [source URL] describes [different detail]. Please check whether this section mixes the pilot with the national exam.”
Include the exam year and official source. A different year’s administration instructions do not automatically establish an error in the year you are reviewing.

For a content correction, the reasoning is usually more valuable than a long description of your device. For an interaction problem, the sequence of actions matters. Use the fields that help explain your particular report.
Before sending, remove passwords, account tokens, student records, and other private information. A fictional address or a redacted example is often sufficient to show the mechanism. Do not paste confidential network configurations into a report.
How a correction is checked
A report needs to be compared with the full question, its stated assumptions, the answer choices, and the explanation. An answer can be technically possible in some network while still failing the specific requirement in the prompt. Conversely, a question may need revision if its evidence leaves two choices equally defensible.
For a calculation, the check includes the intermediate steps and the effect on the answer. For a tool issue, the check includes the selected option, feedback, progress, and score. If a confirmed issue affects another version of the same resource, the related wording or behavior also needs review.
Submitting a report does not immediately change the answer key or a saved attempt. Keep a copy of your notes or downloaded log if you want to discuss the item with your teacher. This page is a reporting guide, not a claim that every disagreement is an error or that every report will receive a response within a fixed time.
