Passed PSMI in first attempt with perfect score of 100%

I set time box of 5 days for myself (2 hrs/day) and was able to achieve it before timebox expiry :)

Day1: 

I started with Scrum Guide. Advise is - do NOT plan to read it in hurry. 

Plan to spare good 2 hrs for reading and understanding it thoroughly. While reading you will come a cross few items which you are not aware of 

or which you find confusing. That's where you have to spend more time (I was able to find blogs for most of these items on scrum.org site iteself).

Registered and bought PSMI assessment. That's all I did on Day1. 

Day2: 

Took scrum open assessment - scored 86.7%

Gone through incorrect answers. Focus on understanding why as per scrum.org it is incorrect (instead of just getting to know the correct answer after open assessment).

Gone through Scrum Glossary. 

Searched blogs with keyword 'Myth' on scrum.org site and read some 5 to 6 blogs. These blogs covers most of the misconceptions.

Day3:

Took scrum open assessment - perfect score

Took Developer and PO open assessments. Got few incorrect answers - analyzed those.

Took scrum open assessment - perfect score

https://www.scrum.org/resources/scaling-scrum - Not mandatory for test and you can skip if you are short of time.

Day5: 

Took actual PSMI assessment in the morning. Was confident of passing the exam - very happy to get perfect score :)
