What is the best resource with mock tests?

Hi, everyone!

I have read a lot of posts here about successful experience of passing the PSM I exam. I found different resources, but I am not sure which one the most updated due to the actual Scrum guide. Some participants on this forum have written, that it can be harmful to training with these kinds of recourses. What can you advice to choose:
1) Mplaza: https://mplaza.pm/product/psm-preparation-practice-test/
2) Scrum Star Academy:
https://scrumstar.com/scrum-certification-practice-exam
3) Boston Agile Training:

Thank you in advance.
