Preparing for PSM II

Hello,

I recently passed the PSM I assessment. The sample assessment in Scrum.org was immensely helpful !

I would like to prepare for PSM II but I was not able to find sample assessments for PSM II or any study material like the Scrum Guide for PSM I.

Can you please suggest reading material, sample assessments and tips that I can use to prepare for PSM II ?

Thanks !
