Trending @Accenture; AWS - SAA Course

Hi All, whoever has completed AWS - SAA certification, can you please guide, from where you have learned online. So that it is easy to understand the concepts in a systematic flow.

I am trying from Accenture percipio videos but it is not very much understandable. Like after introduction, the video starts with s3 bucket straight away.

So i need to know a platform, where the topics / concepts are discussed in a proper systematic way.

Thank you
