Not ready yet Not true. I consider myself somewhat knowledgeable of antennas and related stuff but I failed 1 of 7 practice exams. Some questions are hard to guess the answers to if you dont know them. I mentioned ITU to a General Class ham and his "answer" was International Thermal Units! I'm not kidding either. The advice given to me that I will be taking is if I can consistantly get about 90% or more correct on the practice exams, then I should be ready for the real test. I dont need to get 100% correct but I dont want to "squeak by" either with say a 25 out of 35 for 71.4 % or worse yet fail. Because I DID fail one practice exam I dont feel ready yet.
