I also vote for the Gordon West study guides, they don't bog you down with a lot of theory you don't need to memorize, they give you the actual questions, the pool of answers, the right answer, and a simple to understand explanation of the right answer.
When I first got licensed in 1988, I used the Radio Shack Novice and Tech manuals and tapes, they were also written by Gordon West, when I got back into the hobby this past December, I again got the Gordon West Tech manual to brush up on the things I forgot, and the General manual. With only three weeks to study, I not only regained all that I forgot up to the Tech Level, but also passed my General test with ease.
Hookedon6 is also correct, you do need to memorize some things, and band limits are one of the most important of these, with no less attention given to things like modes, baud rates, power limits, and a lot of common sense safety working with electricity and RF.....
