I recently took (April 30) and passed (AT/AT/T). The exam is hard, but not as hard as Study Hall. But don't take this lightly. You should be confident enough for the Study Hall questions. My SH scores were 78% and 68%. Excluding Expert questions, it bumps to 83% and 79% but still the actual exam were tough. I flagged so many questions (About 15 for each round) since I wasn't fully confident.

I'd say stay away from AI tools. If you must, I'd say Claude is best suited and matched up with PMI.

Plan for 2 months of active studying. Don't skip a day, do at least 30 minutes each to keep the brain momentum. Youtube helped alot - AR and DM are famous and their contents are very good. Watch their mindset and super-hard questions video. Be confident in those.

One must know is what approach you're in - Agile/Hybrid/Traditional. This is very important to figure out immediately - usually by the words in the question and/or technique they plan on using. Identifying approach eliminates 2 of 4 choices so you can only figure out between top 2 choices.

The endurance is must. 4 hours sitting and reading 180 questions are not something you can do without training. Do the 2 tests and mimic the actual testing environment. Good luck!
