I was learning/going thru the GA course a couple of months ago and stopped at section 4.1 "Creating an Account". It seems that the course has completely changed. Am I incorrect, or has GA changed up the materials or at least the order of it?
Yes it has changed, and for the better! Most of the previous videos are still integrated, but the "beginner" and "advanced" courses make more sense. Additionally, the learning is in manageable chunks, there's Google's demo account featured in relevant lessons, and guided tours of analytics that helps solidify the learning.
