PSM I and PSPO I exam

Hi to all,

I attende a PSM I course and made no the exam.
Is the PSMI exam fundamentally different then the PSPO I exam ?
Can I try to make the exam, when having passed the PSMI?
Or are the questions so different and pointing on tools of the PO, which is not described in the Scrum Guide but only handled in the appropriate PSPO trainings and by being expert in using it?

Thanks a lot,
Patricia
