Do I need to read the Nexus Guide for the PSM I and PSPO I?
I'm currently studying for both certifications now and would like to know if I need to do a deep dive into the Nexus Guide / Scaled Scrum stuff. Should I do the Nexus Opens? Anyone know?
No, it's not necessary, and you won't face questions about Nexus.
However, reading about Nexus may help you gain a better understanding of Scrum; particularly if you read something in Nexus that doesn't align with what you believe Scrum to be.
It could be a good opportunity to challenge your own assumptions and ask relevant questions on this forum (or elsewhere) that help you learn.
I agree 100% with Simon.
Not necessary but its good :)
Thanks; I intend to learn about it, but want to dedicate my energy to passing these certification tests first.
