Passed PSM I with 98.8%

Got one question wrong!

The exam wasn't as hard as I had imagined but I then had prepared well.

I studied:
The scrum guide (read twice).
About half of Essential Scrum A Practical Guide to the Most Popular Agile Process by Kenneth S. Rubin.
Some but not much of Scrum Narrative and PSM Exam Guide book.
Management Plaza exam pack (good resource).
Mikhail Lapshin's questions (good resource).
Scrum.org forum.
Nexus Guide (not really needed but it's short).
Scrum Open exam questions on Scrum Master and PO (very easy).


Thanks a million to all the people who replied to flurry of posts, it was a big help.
