The "fixed wing" part kinda threw me - and now I'm even more confused. I
had no idea the tests had yet another classification - one in which gliders
aren't fixed wing aircraft! Geez - I hope there aren't any questions on the
FAA knowledge tests about the FAA knowledge tests - at this point I'd
flunk! :-)

Don't let it throw you, I'm pretty sure they're just using "fixed-wing" to
mean that it's not for helicopters and such.

I can't answer your original question as to just how specific the
endorsement was. But I just wanted to throw in that my instructor was
happy letting me go off and study on my own for a while with various
materials, including the big cheating test-prep book with the entire
question bank in it, and then he signed me off when I said that I was done
and ready to take the test. Depending on your instructor and your learning
style this may not be appropriate for you, but for me at least this
preparation was more than sufficient.
