Please add a category to ideas.arcgis.com which targets the Esri Certification exams.
The Esri Certification exams should have a more detailed explanation of which questions you answered correctly and which ones you answered incorrectly.
The questions should be divided into categories and a percentage indicated on the number of questions you answered correctly.
This will help the candidates that write the exam see where their shortcomings are and where their strengths lie. If they fail they can then focus more on the areas where they were weak in the exam, so that next time they can pass the exam.
