The E20-065 exam, officially titled Advanced Analytics Specialist Exam for Data Scientists, is the EMC exam you pass to earn the EMCDS certification, a credential at the Specialist level. Passing it confirms the skills defined in the official exam outline, and it is associated with related credentials such as Associate – Data Science Version 1.0, Associate – Data Science Version 2.0.
The E20-065 exam includes 60 questions and gives you 90 minutes to finish them. That is a tight pace per question, so get used to reading each stem once, flagging anything uncertain, and moving on rather than getting stuck.
