Hi:   The certification exams do NOT have interface questions. When you start the exam, you pick your editor of choice. If you have been practicing with SAS Studio, then you use SAS Studio for the exam. You don't use 2 different interfaces for the exam. You pick one and stick with it. There are exactly 2 Enterprise Guide demos in the class for our Enterprise Guide students who use Enterprise Guide under their company or school's license. You should be able to do ALL the work in the class and practice for the exam using SAS Studio. Enterprise Guide is not available as a free tool for independent students.   If you have questions about the content in Programming 1, and Programming 2, you can post in THIS forum: https://communities.sas.com/t5/Programming-1-and-2/bd-p/course_discussions OR you can send mail to elearn@sas.com (However, please do not do both.) Pick one approach or the other for help. We have instructors reviewing posts on the Community Forums and we have instructors monitoring emails. We'd like to avoid have multiple instructors working on the same question in 2 different places. Thanks, Cynthia ... View more
