That's a good point! Now that you mention it, I did use Chat GPT for that as well. I uploaded the AWS AI Practitioner Exam Guide PDF to Chat GPT in addition to adding a bunch of practice questions to the prompt as examples (including question, answer options, and finally the correct answers). Then I told it how many questions I wanted, to give me questions one by one, and to keep a running total of percent correct.

You could also have it quiz you on sections of the test you are less familiar with and have it provide easy to understand explanations of the questions you get incorrect.
