Francesco, I see you have not attempted the test yet. I am not sure what simulation you are referring to, but there are NO questions about Nexus on the PSPO I exam. The people who have taken the Product Owner Fundamentals self-paced class have more than an 80% passing rate so those who have taken the class are finding it as a great way to learn, prepare and pass the exam.
