For those that go this route, I found that getting to about 40% mastery for any given test bank is good enough to pass with a safe margin. That is, being able to answer 40% of the questions right every time the same one is presented. Basically you'll find that the Tech is really just "do you know the regulations", the general is "do you know the bands" + basic radio architecture and the extra is "do you know antennas" + some niche/DSP stuff
