Excellent material to make yourself ready for the real test.

Used Dojo tests for AWS SAA as well so I know the standards. Very well written, documented material with great explanation. I will recommend to all who are planning to give AWS Security exam.
One advise to author is to have sticky sessions in place like Udemy (I know its there but I struggled to pause the tests & come back especially with time mode & section wise practice tests, it just resets or ends your test when you loose session).
