I highly recommend the Fast Track books by Michael Burnette. They are $10 each for the Kindle versions.If not, check out this guy's YouTube channel. He is posting videos from his current Technician, General and his most recent Extra class sessions. He even has videos posted from a morse class.
I just got the ARRL guides to go with the classes that he is teaching so that hopefully sometime soon I can test for both Technician and General.
