1. First of all, it is necessary to clarify the scope of GMAT mathematical investigation, including specific mathematical knowledge points, and clarify the basic knowledge points of investigation. The road to review can get twice the result with half the effort, saving time and effort, so the best book to do this is GMAT-OG (official guide): Chapter IV Mathematics Review, which introduces four parts of GMAT mathematics investigation in detail, including: arithmetic (arithmetic), algebra (algebra), geometry (geometry) and application problems (application problems). After the students with good foundation browse, the knowledge points of GMAT mathematics investigation are clear, while the students with poor foundation may not know much about the relevant mathematics knowledge points. At this time, we need another material, that is, Chen Xiangdong's book "Fast Breakthrough of High Score in GMAT Mathematics". But this book can be used as an auxiliary tool, such as some concepts that we can't understand or forget. Search in this book and use it as a dictionary. Therefore, OG is the mainstay, supplemented by "GMAT high score rapid breakthrough". We must master the basic knowledge points of mathematics firmly, so as to ensure that in the next process of doing problems, each problem has ideas and clear ideas.
2. Secondly, based on mathematical knowledge, students can do problems. Students with a good foundation suggest doing math problems on OG first, and brushing PS and DS problems. If the correct rate can reach more than 95%, then congratulations to such students, preparing for GMAT mathematics can save some energy, and the focus of review can be put on oral. For students with poor foundation, the questions on OG are very difficult to do, so Teacher portia's suggestion is to brush the questions of different test sites on Gray's website and master every knowledge point of mathematics firmly, so as to have ideas for each topic quickly and comprehensively, ensure that a topic can be made within 2 minutes and ensure its correctness.
No matter how bad the foundation is, if students can keep reviewing according to this idea, it is difficult to improve their math level. This is the second part of GMAT Mathematics Review.
3.GMAT model test. In the process of model examination, it is a process of checking and filling gaps, and it is also a process of practicing time rhythm, so sum up your own problems in mathematics, such as whether there are any problems in individual knowledge points, the understanding of problems in topics, whether the time for doing problems is slow, and so on.
After understanding these things, plus your own efforts, it is possible to get full marks in GMAT mathematics! The above contents are compiled into GMAT information of pressure reducing valve.
