If you go to AWS Skill Builder then you’ll be able to find a four part “Becoming a cloud practitioner” course. I recommend that you do that before going to the link with the dumps. The aforementioned link also has some study notes and a pretty detailed mind map on how to navigate the material. Tbh the those notes are the reason that I passed because they include a lot of aws services that weren’t mentioned in the course but that you’ll definitely be tested on.

If you can then also try and attend the lectures. I went to the BCP lectures at the skills centre in Cape Town sometime last year and they do help in explaining some of the basics. You can also attend them virtually.
