Disclaimer: We made a question pool available to the public to test their readiness to take the NTC Amateur Radio Exam. The question provided herein are taken from various review materials and are not the actual questions given by the NTC. These questions are only for review purposes. By answering these sample questions, you hereby agree to free CHARL from any accountabilities or liabilities resulting from the use or misuse of these materials. 73’s!
Note: As per rules, the examinee must obtain an average of at least 70% of the 3 elements per class, with no score below 50% in any of the elements. We provided a 40-minute limit to answer each element to simulate actual exam conditions.
