Thank you Whizlab team for your material. I passed with an 882. I especially liked your section tests for the detail and challenge. I did both the current and past section tests. I watched all the videos as well. The 7 practice exams were very helpful, especially the detail explanations for my errors. My first practice test, which was probably the easiest was a score of about 60% and my last test number 7, the night before the real exam, was just above 90%. I scored 84% on the Official practice test just after that.
I also used Cloudguru for some hands on work that was reinforcing. The AWS Official Study Guide was no real help as it lacks any real architecting practice and doesn’t bring the subject matter altogether.
