Hi everyone!
After a few attempts at the first exam - i.e. the "Alteryx Core Certification" - I passed with a score of 90.7% last night!
My advice to others is to stay persistent and never let failure prevent you from retrying, finding out where (in which areas) you need to work to improve (if you do not pass the exam), and learn the "Nooks and Crannies" of Alteryx as you proceed in your certifications.
Before last night's attempt, my scores averaged around 69.2% and stagnated at that percentage until I continuously looked to see where I was having trouble. I also kept on revisiting the Documentation Page and making notes of the 'Nooks and Crannies' of the various tools.
Hope this helps and best of luck to all of you!
