How will the new GRE mathematics change? I hope it will help you prepare for the GRE exam.
According to the analysis of sample questions provided by ETS, it is found that the scope of mathematical knowledge and computational complexity in mathematics have basically not changed, mainly in the number and proportion of GRE mathematical questions and the types of questions. Next, we will make a simple analysis according to the sample questions to see what major changes have taken place in the new GRE mathematics:
The first point is the emergence of question and answer questions, that is, candidates need to directly calculate the answer according to the conditions of the topic, and can't choose the answer from the existing options. This change puts forward higher requirements for candidates' problem-solving ideas.
For example, the average (daily average) of1numbers in a list is 14. If.
The average of 9 numbers in the list is 9, so what is the average of the other 2 numbers?
Numbers? (The arithmetic average of 1 1 number is 14. If the arithmetic average of 9 numbers is 9, what is the average of the remaining 2 numbers?
Analysis: This question examines the examinee's understanding of the concept of arithmetic mean. According to11x14 = 9x9+2xa, we can get the answer.
It can also be seen from this topic that some statistical values (such as arithmetic mean, range, standard deviation, median, etc.) are required to be understood in the reformed GRE mathematics. ) has improved.
The second point is the emergence of multiple-choice questions, which require candidates to choose all the answers that meet the meaning of the questions.
For example, in triangle ABC, the measurement of angle A is 25, and the measurement of angle B is 25.
Greater than 90. Which of the following can be used to measure angle c?
Indicate all possible values.
A. 12 B. 15 C. 45 D. 50 E.70
Analysis: This question examines the basic properties of triangles: the sum of internal angles is equal to 180 degrees. According to the meaning of the question, the sum of angle A and angle B is greater than 1 15 degrees, from which it can be concluded that A, B, C and D are the correct answers.
It can be seen from this question that the mathematical knowledge of GRE mathematics itself has not changed much, so this question only increases the complexity of candidates' thinking and requires candidates to be more careful and serious.
The third point is that there is a judgment question, which requires candidates to judge whether an equation or proposition is right or wrong.
For example: symbols? Represents one of the four operations of addition,
Subtraction, multiplication and division, and 3? 1 = 3.
For each of the following equations, indicate whether the equation must be
True, it must be false, or it may be true or false.
equation
It must be true.
It must be fake.
It may be true or false.
6 ? 2 = 3
6 ? 2 = 4
6 ? 2 = 12
Click on your choice.
Click the answer box and enter a number. Backspace deletion.
ETS self-defined content often appears in GRE mathematics. According to the meaning of this question, the symbol "?" Represents one of the four operations of addition, subtraction, multiplication and division, 3? 1=3, what can be deduced from these known conditions? It can be a multiplication symbol or a division symbol, so it is two cases.
What about the first equation 6? 2=3, in? It means that the time is right, but in? Stands for multiplication error, so the first formula should be possibly true or.
False (may be right or wrong);
The second equation 6? 2=4 regardless? It is neither representative nor correct, so the second formula should be false;
The third equation 6? 2= 12 inch? It means that multiplication is right, but in? Stands for time division error, so the third formula is the same as the first formula, which may be right or wrong.
The above three points are the concrete contents of the main changes in the new GRE mathematics. Candidates can master it with a little practice. I hope candidates can get full marks in GRE mathematics.
