Agreed but I don't know Ohm's Law, how to do Morse Code or much technical about radios. I have been around CB's a lot even remember old issued call sign back when they did that...
Good News! The CW test is gone. Also, you don't need to know ohm's law, the relationship between frequency and wave-length, or anything about antennas. All you need to do is learn all the answers. For example, to get a tech license you must answer 26 questions correctly out of the 35 on the test. Those 35 questions are drawn from a pool of 423 publicly available questions
. You just study the questions, take practice tests, and keep doing that until you can easily pass the practice tests. BTW, out of the 423 questions, maybe 25% are pretty much common sense, and another 25% make total sense once you see the answer. So, you really only have to work on less than 1/2 the questions.
There are a lot of online resources, for free, and for fee.
