Absolutely essential practice before taking the real exam!

This is my second time using the Tutorials Dojo practice exams. After passing my original AWS Solutions Architect Associate exam with the TD practice exams, I used them again for my re-certification exam. My scores on the TD practice exams were 80%, 72%, 76%, 78% and 81% while my passing score on the real exam was 80% so the TD exams were very accurate for predicting my results. The topics on the TD practice exams were reflective of the topics on the real exam, so I feel the practice exams prepared me by focusing my studies on the right topics.
