Yes, we reuse some courses in many (20+) learning plans.

Thank you, I thought so but wanted to make sure. 

@Sgrullon12 just keep in mind that if any users are assigned other LP that contain a course they already completed, it will show as completed when assigned (unless you choose to archived the completion of the course that was done outside the LP. Courses inside LP;s and LP cannot be archived at this time

Ahh yes, So the completion status stays the same on the course level no matter what Learning plan its attach to. 

@Sgrullon12 correct...sometimes it’s in your favour and sometimes it’s an annoyance...
