Taiyuan University of Technology computer re-examination is divided into interview and written examination. The written test is in the afternoon. The written test seems to take three hours. First, it's a half-hour listening test. Listening comprehension is similar to CET-4, that is, long dialogue and short dialogue, with almost 20 multiple-choice questions. The rest of the time is to take professional courses, 100 multiple-choice questions, and each of the five courses has 20 questions. The five courses are discrete mathematics, object-oriented programming, database, software engineering and compilation principle. Because the questions are multiple-choice questions, they are the most basic knowledge points, but they are still quite comprehensive.
