Hello @dunnkevi ,
Fundamentals course is being deprecated. Ability to register for this course will end on October 25th, with access ending on November 30th. If you have already completed or will complete 7.x version while it is available, this will serve as a prerequisite just as 8.2 version because there is no significant difference between those versions.
