Hi Ashley,
While PMI's idea to develop Standards+ is good, the implementation (and user guidance) is lacking. It's just a "big pot of stuff" in which we all have to "muddle about". So until PMI makes some serious changes in the available filters there really isn't a satisfying answer that I can give you.
So... Your best approach is simply to use it as a reference. If you come across something that you want more detail on, then look it up and review the information. We also include it in many of our simulator questions as a reference. So use it to look up information in case you get an answer wrong.
