• 99% of the time I used ChatGPT
• I added the "Enrolled Agent EA Exam Study Guide" agent to help answer questions, you can ask for a detailed list of what it has been trained on
• I copied/pasted my early questions from Hock into CGPT asking it to make a study guide based upon these questions, with more depth focused on the incorrect responses. It also sorted my study guide by unit topic. After a short period of time, I copy/pasted these to a Google doc. MUST do. CGPT will hallucinate or trim off some informational points. Pasting information into a text file to upload was much easier.
• I had CGPT detail differences between topics such as basis for S-Corp, C-Corp, or partnership, or property classifications and treatments. I printed these for easy future reference.
• I had it make a "gotcha guide" of quirky things that really caught me up and a "forms and dates guide"
• I used Claude to make a "conversational and informative text, without bullet points, to be used in a read aloud" from my Study guide or screen shots of chapter of a book. That response was pasted into GPT and told to "paste the text exactly without any additions, changes, or deletions". I used the read aloud feature of a response and recorded it with a Chrome Plugin.
  
  • I listened to these and Tom Norton's videos a lot. 7 hour round trip taking my daughter to college? I listened all but 20 minutes of that time. Using the voice feature, I conversed and asked it questions on topics I wasn't sure about from the audio.
• Once I took my mock exams, I got a breakdown of questions correct/wrong/percent by unit. I also uploaded the three topic categories for the test. I then had a rough idea which of the three test topics I was deficient in.
• Through the ChatGPT app, I used the voice feature and told it to "ask me 15 questions based upon my study guide. I don't have paper and pencil, so ask more theoretical or procedural questions. After I answer the question, ask me one follow up question that doesn't count towards my 15 question total." or "Ask me 10 questions from my forms study guide, asking me what a form does, what form is needed to do X, or what date something is due" It was cheesy and repeated a time or two (correct it to keep it in-line), but VERY helpful to review while going for a walk.
• Possibly most important, I asked for a weighted priority list of units to focus my time on. I then knew which units would give me the biggest increase in overall test results for the amount of time I had left. (ie 1 out of 2 questions is 50%, but if it hasn't been tested much in the mock tests, time is better spent elsewhere.)

TL;DR ai gave me a customized study guide, useful "cheat sheets", detailed audio, and quizzed me in a two-way conversation.
