How did you prepare for AWS Certified Solutions Architect – Associate Level certification?

I receive my AWS Certified Solutions Architect – Associate Level in Feb 2018. First, I think a course on Online Courses – Learn Anything, On Your Schedule | Udemy. Here is the link: AWS Certified Solutions Architect – Associate 2018

Second, I took the AWS CSAA Practice Test from whizlabs.com. It is a paid course but I think it is worth it.

Those two are enough for me and I passed it on the first try albeit barely. I also made sure to redo some of the labs on the udemy course so I can remember it more.
