PSM Questions - alternative sources to study?

Hi everyone!

I've been studying for PSM I and I want find other way to test my knowledge before take the test.

Nowadays I know the Scrum.org Open Assesment (4 times with 100% using less than 8 minutes each) and the book Scrum Guide (there is two tests based on PSM I and I got 100% in both).


I want to know if someone know another "Open Assesment" or another book with questions where I can test my knowledge...


I tryed find this in this forum but I couldn't.

Thanks all!
