The written test difficulty of advanced interpretation is equivalent to that of TEM-8 (even more than TEM-8), which requires candidates to have relatively solid listening, speaking, reading, writing and translation skills and common sense of Britain and the United States. The main review reference materials are the official advanced listening course (third edition), advanced translation course (third edition) and advanced interpretation course (third edition), as well as real questions (at least in the last four years). The landlord had better do a set of real questions first, and get familiar with the questions and requirements, so that you can know fairly well when reviewing. Of course, if you are self-taught, you may not be conscious and efficient enough. You can also attend a training class and the exam will be charged correctly. I recommend a place for you, Suzhou Translation Hall Music, which specializes in training middle and advanced interpreters. Good reputation, the landlord can go and find out.
