Upgraded to the AWS Professional level from the Associate level exam I took 18 months ago.
I estimate I spent about 10 days preparing:
* 3 days of AWS classroom training
* 3 days of watching a Cloud Guru videos
* 2 days reading AWS whitepapers
* 1 day watching AWS deep-dive videos
* 1 day doing mock exams
Glad I did it, but mostly glad it’s over so I can do something else. 🙂
