You can build a CPA test bank with ChatGPT.

I sell a CPA test bank, and I'll start by telling you that you can probably build your own. Fifty dollars of API tokens, or a twenty dollar ChatGPT subscription and a lot of copy-paste. That's a real option and I'm not going to pretend it isn't. So I did it on camera. Fresh browser, incognito, no account, no prior context. One prompt: "Write me a CPA exam REG multiple-choice question on the 2026 SALT cap. Four options, a rationale under each, and cite the authority." First generation, first attempt. No retries, no cherry-picking. What came back looks excellent - clean stem, four plausible options, a rationale under each, a code citation, linked sources. Then the rationale under option A does the arithmetic and concludes, in its own words, that B is the correct answer. One explanation into the question and the answer key is already wrong. That is why the bank exists. Roughly 28,000 questions generated. More than 10,000 deleted. Every survivor blind-solved by two models that never saw the answer key, then reviewed by me. Oregon CPA #14907. Find a wrongly keyed question in the paid bank and I pay you $50. The honest trade: fifty dollars and your total vigilance, or fifty-nine a month and the vigilance is on my desk.
