First of all, analyze the main points of GMAT math exam.
1. Different units of measurement refer to different objects. Usually, English units are converted, but metric units such as centimeters are not. In addition, the conversion of time, the radius and diameter of a circle are all test sites where measurement units are prone to errors.
2.PS problem: it is necessary to see clearly whether to calculate the ratio or the numerical value; Comparison depends on who is asking and whose comparison.
3. See clearly whether the broken part is discounted or the discounted price.
4. Topics usually contain some implicit conditions, such as integer, considerate, different, non-zero and so on. Any conditions must be made clear.
5.DS question: When preparing to choose C, we must see whether B alone is enough.
6. Sometimes it is not difficult to calculate the question, but you should see the requirements of the question clearly and then answer the question according to the question.
7. Pay attention to the hidden conditions of the topic. Common sense will be used here. Some problems are only a simple solution from a mathematical point of view, but they are another solution to solving life problems.
9. The integer condition is given. Contrary to the above, there are no conditions attached to such questions. Sometimes, it depends on whether the question involves integers. If it is not, don't think it is an integer.
Second, GMAT math preparation skills
1. Learn to use Internet resources.
When preparing for the GMAT math exam, candidates are advised to make more use of online resources, such as the handouts of some exam remedial classes, the rapid breakthrough of GMAT math problems, and download more useful materials for them to use.
Use the official guide
For GMAT math problems, candidates must first be familiar with the types and requirements of math exams, so they must use the official guide. Generally speaking, the topics of the official guide are relatively simple, especially in the front part, which requires candidates to think carefully later.
3. Choose the right counseling materials
When preparing GMAT math problems, it is recommended that candidates learn to use OG and other materials and be familiar with answering methods and skills.
Some topics in the counseling book will be more difficult, but don't lose confidence in yourself at this time. You should advance despite difficulties and make every question clear, because there will be many questions in the exam. When these problems are solved, you will naturally get high marks in the exam.
4. Learn not to care
In the preparation process of GMAT mathematics, there are many problems that will waste candidates' time and energy, such as trigonometric function.
In fact, candidates don't need to care too much about this part. Never take a detour when encountering such a problem, but firmly believe that there are simple ways to solve it.
5. Pay attention to the role of machine classics
Candidates should make full use of the online resources of machine classics, repeat the machine classics they can find in the month several times, and make every GMAT math problem clear. For those questions that really can't be answered, you can ask the previous candidates.
