The question bank just changed as of June 30. I have not seen any updated study guides as of yet.
The easiest way to get your ticket is to use the HAM Test Prep App on your phone. Just keep taking all the questions and memorize them. If you do it enough, you can get the 26 right after a while without having to know all the formulas and such.
I have had 4 people get their tickets this way and I got as far as General like that. Joined a club afterwards and let them explain what I really needed to know to operate a set. Now working on my Extra.
