For the most part I absorbed a lot.  But there were hiccups -- information appeared on the subtests that hadn't been presented yet in a couple instances, and more time could have been spent clarifying the confusing types of airspace -- I know it was covered, but I couldn't retain it well, so perhaps a different approach.  The videos are usually fine but often could be replaced/augmented by the same material in a quick chart -- I was reluctant to rewatch a 9 minute video to find a missing fact, and wound up toggling to a Google search box.  But overall I suppose it did what it was supposed to.  Will see how I fare on the actual test now.
