Google Analytics advanced segmentation and IQ test

Today I finally learned something that I knew was possible, but never needed to figure out the specifics: “Google Analytics Advanced Segmentation.” First I want to share some definition so the previous four words would mean something to you if it doesn’t.
“Google Analytics is the enterprise-class web analytics solution that gives you rich insights into your website traffic and marketing effectiveness.”  Or to put it in lay man terms: using this tool can tell you how many visitors your sites have, where they come from, how long they are staying on your site, what pages they are viewing there and much more information about the visitors and the site usage.
“Advanced segments allow you to choose what types of visits you want to be considered when generating the data for a report.”  For example you can create a segment to see who is coming from a certain country or city, who have already visited the site last week. The combination of possible metrics and dimensions to include in the segment is quite high. And now I know how to create/combine them.
Having been energized by my new knowledge I checked out what else I don’t know in the realm of Google Analytics. This search led me to “Google Analytics Individual Qualification (IQ) test.”  I haven’t decided whether I will take the test that would cost $50 and is valid for 18 months. But I know that I will work my way through Conversion University’s online course that test takers use to prepare.
