3. Deduction judgment: Deduction judgment refers to judging the wrong option selected by the candidate according to the scoring standard. Generally speaking, the marking system will automatically determine the wrong option selected by the candidates according to the set deduction points.
Introduction to mathematics in the new college entrance examination
First, the change of examination methods.
1, test paper form
The paper form of the new college entrance examination is very different from that of the old one. The new college entrance examination mathematics adopts modular examination, which is divided into a volume and b volume, and each volume has two modules. However, the old college entrance examination mathematics test is a test paper, and there is no concept of modular test.
2. Examination time
The examination time of the new college entrance examination is longer than that of the old one. The new college entrance examination time is 150 minutes, and the old college entrance examination time is 120 minutes.
3. Examination form
The examination form of the new college entrance examination has also changed. The new college entrance examination mixed calculators and non-calculators, while the old college entrance examination prohibited the use of calculators throughout the whole process.
Second, the new college entrance examination mathematics answer points to pay attention to
1, pay attention to the topic.
Observe keywords carefully to avoid losing unfair scores. The simpler the question, the more careful you should consider it. The chosen answer is 100%. If you are not sure, you would rather not choose than make a mistake.
