Today I succeed in my AWS CSA associate. The third one after sysops and devops. Tests from whizilabs were a good start where to learn and practice, well done explanations, but in more than 500 questions in this labs, I didn’t even find 1 question in the real exam!
So my suggestion is to study in deep each topic and understand the concept, going through amazon documentation. Learn in memory the questions won’t help at all and most likely you will fail!
Score: from 100 to 1000
To Pass the exam you need at least: 720
