I just got my licence a couple weeks ago. the method I used was --- the audible, "fasttrack to your technician licence" by Michael Burnette and practiced on
qrz.com with the practice tests.
When I first started I was doing the tests and not really understanding the topics, once I listened to the book things started clicking and the practice test scores increased. It took me a while but I was not totally consistent in studies, but once I buckled down and talked to my wife, she just said pick a date and go! LOL it worked, I focused and got it done. I drive a lot so it was good with the audible, probably listened to the book 3 times set on 1.5 speed and sometimes distracted with stuff, thus the multiple passes.
Good luck to anyone going for it.
