The supporting courses section is confusing.
The supporting courses are totally optional. If you have trouble with a particular exam domain, I would then check out the corresponding mini course.
In my opinion, the "ACG Learning Paths" PDF document that is provided as a resource in this course is misleading. It also conflicts with the AWS Architect learning path that is provided on the website (https://learn.acloud.guru/learning-path/aws-architect). The AWS Architect learning path describes a completely different list of courses that one should take prior to arriving at the SAA-C02 course. I personally have followed the latter path and I would feel a lot better if one of the website officials could approve both my claim and my approach. Moreover, there seems to be an old version and a new version of the SAA-CO2 course. I find this very confusing as well. I also hope an official can come out and explain why there has to be two courses and recommend the right one to take. Why not remove the old course?
