Hello Jeff,
I'm not sure if you have visited the SAS Certification Web site yet or not but if you are considering this exam, you can get an idea about the content and the difficulty level of the content that is covered on the exam by visiting: https://www.sas.com/en_us/certification/credentials/bi-analytics/visual-statistics-84.html
You can look at some sample exam items and download the exam content guide which details the topics covered on the exam. In addition, we provide information about the recommended training to help you prepare to take the exam. We also offer a free practice exam although we strongly recommend that you study first and then use the practice exam as a way to determine where you may have some knowledge and skills gaps. Finally, we recommend that a candidate have several months of practical experience using SAS Visual Statistics.
I hope this helps.
Kind regards,
Becky
