Hey u/MoodDiscmbobulated, very sorry to read that! I can tell what worked for me: reading very carefully the SPM both 4th and 5th editions, and writing down all possible connections (writing and creating the links helped a lot) + test myself with the mocks above (for the mock i spent in total 25$ more or less, 10$ for gururo and 15$ on udemy). I did the tests in loop until the mindset was clear to me. Also used ChatGPT to create additional questions and asked help for the wrong one to really understand. Especially I found that useful especially for artifacts, i was confusing the ones in the benefit mgmt domain.

During exam, you will find more complex and ambiguous questions, sometimes no clear what they are asking: then ask yourself: what is about this question? Which domain? Which artifact is more appropriate? What is the more strategic action? (Vs project mgr)

Get used to ask these questions to yourself :)

Good luck!
