    Mihail, thanks a lot for the tests.
    Passed PSM I with 95% 🙂

      I am glad I could help you.
      Do you remember what was the topic of the non-obvious questions?

    Hi Mikhail,
    Thank you for this blog. I have a quick question. Once we clear this PO certification is there any yearly maintenance test that we need to keep up with?


    1. mlapshin (Post author)

      Hi Anu,

      No, there are no any maintenance tests. The earned certification has no expiry date.

    Thank you so much for providing assessment for PSMI ..I was able to pass exam in my first try today..I have no experience with scrum other than reading through scrum guide and your assessment gave me confidence to sit for the exam..Some of the questions were confusing due to the fact that I didn’t have real life experience ..Hope this takes me somewhere..our organization is going on agile direction and scrum is new to many people.. Any recommendations on what other certification would be helpful for newbie like me?

      Hi Merina,

      Thanks for using my quiz and sharing your success.
      You could pass the PSPO I exam.


      1. msharma2

        Thanks Mikhail!! Will definitely try it

      2. msharma2

        Aside from Scrum Guide Document and your PSPO assessment, is there any good books/docs that I could use to prepare for PSPO exam? I tried taking your assessment and felt that some of the questions/answers did not come from Scrum Guide document. For example, there was one question about KVA that I was not familiar of. Would appreciate your help.

        1. mlapshin (Post author)

          Hi Merina,

          You are right. The PSPO exam contains questions that are not directly answered in the Scrum Guide. So, you need to learn more about product owner role responsibilities. For me reading the following article: The New New Product Owner and Evidence-Based Management Guide brochure was enough to pass the exam.
