MyOpenMath Answer Key: What It Actually Is and How to Use It
MyOpenMath doesn't generate answer keys the way most people expect. If you're looking for a single PDF with every correct answer for your whole course, you won't find one there. The system randomizes questions, so each student sees a different version. That means the "answer key" is really a per-student, per-problem display that shows the exact correct value the system accepted for that specific attempt. I've been working with MyOpenMath in various institutional settings for a while now, and this is probably the most common point of confusion I see. Students come in thinking an answer key means a static list they can against. Instructors think it works like a textbook solution manual. Neither is right, and that gap causes a lot of unnecessary friction.

Here's how it actually works. When you're an instructor logging into MyOpenMath, you pull up a specific homework assignment. There's a tab or link labeled "Answers" or "Student Results." Clicking that opens a spreadsheet-style view where each row is a student, and each column is a problem. The cell will show either a checkmark if they got it right, or the correct answer if they got it wrong. Some setups also show the student's submitted answer alongside it. The thing people miss is that the answer values are unique to each student's randomized version. Student A might have a question asking for the y-intercept of a line with slope 3 and x-intercept 4. Student B might have slope -2 and x-intercept 6. Both are from the same question pool. The answer key reflects that. It's not one answer, it's dozens of answers depending on how many students are in the section. There are a few formats you can export from. CSV is the most commonly used because it opens cleanly in Excel or Google Sheets. You can also print a PDF version directly from the browser, though the formatting tends to be cramped if you have more than 30 students. I usually recommend the CSV export and then filtering or pivoting based on which problems had the highest failure rates.
One edge case that catches people off guard: if a student has multiple attempts on a problem, the answer key typically shows the answer from their most recent attempt, not necessarily their first. Some instructors set up MyOpenMath to only count the highest score, which means the displayed answer might correspond to a later try. If you're trying to debug why a student thinks they got it right but the system shows something different, check the attempt history separately from the answer key view. For students, the answer key is less visible but still accessible after a homework set closes. The system usually displays the correct answer next to each problem they got wrong. Some institutions configure this to show immediately, others delay it until the due date passes. If you're a student wondering why you can't see the correct answer yet, that's almost certainly a timing setting your instructor controls, not a system bug. A counter-intuitive thing about MyOpenMath answer keys: they don't always match what you'd get from a textbook solution manual, even when the problem looks identical. This happens because the randomized parameters can produce numerically equivalent but structurally different answers. For example, a factoring question might accept (x+3)(x-3) or (x-3)(x+3), or a simplified fraction might be rendered as 4/6 instead of 2/3 depending on how the student entered it. MyOpenMath usually handles these equivalences, but the answer key will show whatever form the system evaluated as correct for that specific input path.
Get the Full Details
If you're an instructor trying to build a traditional answer key document for yourself—maybe to grade a paper-based quiz that uses the same question pool—there isn't a built-in export for that. You'd need to go into the question editor for each problem in your assignment and manually note the answer variations. It's tedious, and most instructors end up skipping it because the in-system answer key covers what they actually need for grading. The one scenario where the answer key completely breaks down is with open-response or essay-style questions. MyOpenMath has limited support for free-text input, and when an instructor sets up a question that requires a written explanation, there's no automated answer to display. Those show up in the results as blank cells or "not graded" depending on the configuration. You have to manually review those. Another limitation worth noting: the answer key doesn't capture partial credit information well. If your institution uses step-by-step problems where each step is worth partial points, the answer key might show a checkmark for the overall problem but not break down which steps were correct and which weren't. For that level of detail, you need to look at the individual problem submission log, which is a separate view inside each student's record.
Exporting the data regularly is something I'd recommend regardless of whether you're planning to use it immediately. The CSV files are useful later when you need to build reports for departmental reviews or accreditation paperwork. Having a clean export from midterms and finals saves you from scrambling when those requests come in unexpectedly. There's no single download link because the answer key isn't a static file. It's a dynamic view tied to your specific course instance, your specific assignment, and your specific student roster. If someone tells you they can send you a MyOpenMath answer key file, they likely mean a screenshot or export from their own course, which won't be useful for yours. The system simply doesn't work that way.
