I just passed today. I watched the cert videos several times, commuted to work listening to lectures, took the simulation test about 8 times – getting into the %90’s towards the last few, then using the links to read more about the ones I missed. Watched a lot of the AWS re:Invent videos. Read a few FAQ’s, less white papers.
I also passed Network Specialty and SAA first.
Thanks ACG! See you at re:Invent in Vegas ’19
Congratulation planning on sitting for it this in a few days
