    For everyone taking the exam, don’t stress out! It’s very easy. Learn the basics of AI thoroughly, what classification regression and clustering is. At least 5-6 questions based on that
    Next make sure you’re thorough with the 6 principles of AI. 3-4 questions
    Later the cognitive services of Azure. Learn all the services related to Azure ML properly and you’ll pass with flying colors! Good luck☺️

Although it is missing some topics, not a lot, but definitely missing a few topics. I think the confused matrix and some I can't remember. Thanks man! I owed you one. I dropped a like, subscribed and hit the notification bell. You just earned a loyal subscriber.

I am not at all familiar with AI or Machine Learning and am on a Project Management path at my workplace rather than an Engineering or Technical path, but the Azure Page as well as some other do say, AI-900 is a Good to have Certification at most for a Project Manager.

Now I will work toward AZ-104 to become a proper cloud system engineer, and most importantly that I want to advance my career path.

    Great video as always John. I've read the MS press book, done the MS learn modules and with this video I should be fine to ace the exam on friday. This has become my standard prep and I've managed to get great scores on AZ900, SC900 and MS900. So naturally I went the same route with this exam. Next up will be DP900, AZ104, one of the associate security certs (haven't decided yet) and getting my drivers license before we start singing Christmas carols. (rule 4!!!!)

John Savill is a wonderful teacher and mentor who has helped me virtually along the way. In his videos, he has provided valuable study material and clear explanations of complex concepts. He has also made learning fun and engaging with his video tutorials. I have also done a good deed by sharing John's videos with your colleagues. John, these videos show that you are generous and willing to help others learn and grow. You are a positive influence in the community and a role model for other aspiring AI professionals.

    936/1000 using this video and a LinkedIn Learning course by Emilio Melo (through my library). This video is a good overview that ties everything together. If your recall is excellent, this video may just be enough. For me, I needed the LinkedIn video for detailed reinforcement. I skimmed the MS Learning Path, but got insanely bored and just clicked through it - it's way overkill. The Learning Path was good at explaining the 6 fundamentals of responsible AI, however. Thank you, John! This video was super helpful in tying everything together and creating a mental model of the material.

    So I searched for AI-900 cram just out of interest to see if somebody was doing this cram video in a different way, I found one, they went on for about 20 minutes of basic intros and then suggested we watch John Savill's video for the cram on AI-900. LOL
    I should have just searched within your channel.
    Thanks BTW, I passed mine today.

    I watched your video to take the test today, I'm from Brazil and I actually started studying English in the middle of March, I managed to pass and now I'm certified, this video was essential.
