The GRE math exam only tests these abilities:
The mathematics part still pays attention to the same mathematical concepts as before, but it will introduce more life scenes and highlight the examination of candidates' ability to interpret numbers. Mainly manifested in:
1. Whether it has the basic concepts and skills of arithmetic, algebra, geometry, probability and statistics;
2. Can you explain and analyze quantitative information?
3. Whether the problem can be solved by mathematical model, and whether the ratio of life scene problem to data interpretation problem can be improved.
The GRE math exam only involves these questions:
1. Examination form
The math part of GRE test has two sections, each with 20 questions, and the time for doing the questions is 35 minutes.
Examination questions
(1) An expression based on an option or answer.
From the form of options or answers, 40 GRE math problems can be divided into the following four categories: quantitative comparison questions, single-choice questions, multiple-choice questions and digital fill-in-the-blank questions.
(2) according to the topic setting
Most of the small questions in GRE mathematics are independent, which we call discrete quantity problems; There are also a few questions based on the same chart or data, which we call data analysis questions. The 40 questions are divided into two parts and distributed as follows:
Examination scope
(1) Arithmetic: the properties of numbers and the changes and applications of four operations. This sub-topic is generally quite easy, accounting for about15% of the exam questions;
(2) Definition: including words and formulas solved by definition, accounting for about10% of the test questions;
(3) Algebra: Calculations based on word algebra are mainly algebraic equations and algebraic inequalities, accounting for about15% of the test questions;
(4) Text questions: Do some very simple operations by reading lengthy narratives, accounting for about 20% of the questions;
(5) Geometry: including the calculation of angles, perimeters and (table) areas of planar geometric figures such as triangles, quadrilaterals, circles and even polygons;
(6) Chart title: Use statistical charts (mainly including circular charts, bar charts, linear charts, tables, etc.). ) Through analysis and calculation, some problems that need to be solved by candidates are found, accounting for about 15% of the problems.
GRE candidates need to spend at least a few hours (preferably a few weeks) to get familiar with the test sites of GRE. Although the contents of the investigation coincide with SAT, the concepts of algebra and arithmetic in GRE investigation are more advanced than SAT. Because many test sites need candidates to memorize formulas and problem-solving processes, it is worthwhile to spend money on a good GRE math course.
Second, is GRE mathematics difficult? These questions are difficult.
Understand the problem
Error performance:
1. I can't read the literal meaning at all.
I can read the literal meaning, but I can't finish it within the specified time.
3. I can read the literal meaning within the specified time, but I can't quickly sort out the mathematical model or problem-solving ideas.
The so-called understanding problem is actually that you can't understand the topic. This kind of mistake is fatal, but it is particularly easy to be ignored by some students who think they have good thinking and strong logic. It's a pity that you will make mistakes because you can't understand the topic.
Knowledge point forgetting
The performance of making mistakes: I can understand the topic and have a general thinking direction, but I have no impression on the tools for completing thinking (such as the formula for describing statistics, the two processing methods of sets, the formula for permutation and combination, probability, etc.), or I have an impression but I can't master it systematically, which leads to the final failure to complete the topic.
This is actually a mistake that should not have happened. The mathematical knowledge points of GRE test are fixed, which does not mean that some new contents are suddenly added. As long as the candidates are fully prepared in the review, such mistakes should not happen.
Thinking trap
Wrong performance: I can understand the topic and know the ideas and tools used, but I added conditions because I added my own subjective or past common sense. In this case, there is a deviation in solving the problem.
A common kind of mistake, commonly known as taking it for granted. When doing the questions, candidates subconsciously fabricate some common sense as conditioned brains, and finally get the wrong results. Pay special attention to the math part of the GRE test, solve the problem completely according to the conditions given in the topic, and don't add your own subjective common sense.
A hasty question
Error performance: calculation error, taking the "height" of triangle as "edge" and so on.
Needless to say, everyone must have made this mistake. Summarize the solutions, concentrate the sloppy problems together, look at them often, and ensure that the same type of mistakes will not be made again.
waste time/waste of time
Misperformance: spending too much time on one topic will eventually lead to insufficient time on other topics.
There may be many solutions to the same problem, especially the problem of sufficient data. It is easy for candidates to be unnecessarily complicated in the process of solving problems. Although they can finally get the answer, it will affect the time allocation of the whole question.
