Self organizing teams

Dear people,

I made the PSM 1 exam and unfortunately failed by scoring 83%. The graph provided by Scrum shows that I scored bad on the self steering / self organizing team topic with a score of 71%.
I was looking for more information about self organizing teams, but I can't find much in the scrum guide or on this forum.
Can anyone give me some tips in where I can find more material related to self organizing teams in Scrum?

Thanks in advance!

Regards,
Robert
