Self-study for PSPO II

Good morning everyone,

I passed the PSPO I assessment and I would like to consider the PSPO II now. Unfortunately, for budget and time reasons, I may not be able to attend a training course.

What is the level of PSPO II assessment? Can anybody provide some insights on it? Has anybody attempted and passed with only self-study? Any suggestion to share?

On my side, I have a business administration and IT education. The former should help much on the team, organizational behavior, and theory of leadership aspects.

Thanks in advance,

Daniele
