I scored 873/ 1000. I studied for 5 days (approx. 3-4 hours per day) and took copious notes which ChatGPT further refined for me. In addition to the 'Introduction to AI in Azure' Learning Path, and their practice exams, I also watched the latest John Savill's youtube cram sessions which were excellent.
The exam content included a lot from the exercises - from Azure OpenAI, Foundry, AI Services, Cognitive Services etc., which I had very hastily completed, so make sure to spend a bit of time on those. There was a lot of questions on Generative AI - more than I had expected.

It was not easy and I would have preferred to have studied the content over several weeks instead of cramming this way but I received a free exam credit from Microsoft and had to use it by June 21 (and I'm travelling for the week starting tomorrow).

Edit: No prior experience or knowledge in AI or Azure

I passed the AI-900 today. I thought it would be a good complement to my other Azure certs. I used MS Learn, John Savile videos, Whizlabs and TD for the practice tests. Overall, I enjoyed doing the course and learning about AI. My focus is more on AI related cybersecurity \ governance than engineering so will not be following up with Azure AI Engineer.
