In what year did the comprehensive questions begin? 199 contains mathematics, which is the primary application of mathematics knowledge in high school, junior high school and primary school. That is to say, we have all been exposed to these knowledge points in our previous educational experience, but we just changed our way of thinking to test you. Therefore, it is often called the first number in the postgraduate entrance examination party. Yes, as the name implies, it is elementary mathematics. This initial number is not as complicated or difficult as the advanced number. The investigation of the initial number is quite flexible and logical, which embodies the creativity of students and examines the ability of students to combine, construct and apply what they have learned. Simply put, the initial number is easier than the high number, but this is the logic in mathematics. The logical reasoning in 199 includes three parts: formal reasoning, argumentative reasoning and comprehensive reasoning. Logical reasoning questions and options have a large amount of reading (words) and information (information points). Reading speed and the ability to grasp key information are the basic abilities to do this part well, that is to say, not only do the questions quickly, but also accurately. Of course, these abilities can be acquired through training.
