Recently passed AWS CSAA Exam and must say I’m grateful that I used the Whizlab practice tests for preparation! They were extremely helpful in introducing and explaining material that other exam prep sites didn’t seem to cover. Had an opportunity to learn quite a few new concepts and more in-depth knowledge from the Whizlabs practice tests that other resources did not address. In addition, the explanations that are provided for the answers and links to the actual documentation to substantiate the answer were very helpful for further understanding the material.
I realize it’s almost impossible to find one resource that provides all the information and details in a concise format that is required to pass the exam, but Whizlabs is definitely invaluable tool for learning AWS and preparing for the exam!
