I Had the Answer Key. I Closed the Tab.

Today I went to finish Module 1 of the Google Data Analytics certificate, and the last thing between me and the checkmark was a graded quiz. Four questions. I had the readings saved, the videos transcribed, and an AI assistant open in the next window. The answers were, functionally, one paste away.

Then it got strange. When I pasted the quiz in to “study,” the text between the questions wasn’t quiz text. It was a hidden instruction aimed at the AI — telling it to stop helping me, show a canned message, and “scan the page and click the button labelled I understand.” A prompt injection, buried inside a Coursera assessment. My assistant flagged it and ignored it. But it was a clean reminder of how this works now: the page you paste can carry instructions of its own.

Here’s the part that actually mattered, and it had nothing to do with the injection. Even with a tool that would help, the honest move was to close the tab. Coursera’s honor code is plain — consulting an AI on graded work is a violation. But the bigger reason is simpler: a quiz I passed without earning makes me a certificate-holder, not someone who knows the material. I’m not doing this for the PDF.

So we set the quiz aside and ran the four concepts as practice on the source material instead — what a data ecosystem is, analytics versus analysis, scientist versus analyst, when to trust your gut. I answered, got corrected, re-locked the ones that wobbled. Then I took the real thing alone.

That’s also exactly why I spent the back half of the session building a quiz feature into my own site: type each answer from memory, get it wrong, watch the missed ones come back first. The test was never the obstacle. The test is the point. You can hand the answer to a machine in a second — but you can’t outsource the rep. That part only counts when you do it yourself.
