First, the reasons for unsatisfactory performance
1. Weak language foundation, poor reading comprehension, or slow reading speed, which affects problem solving.
2. Forget the knowledge points of mathematics, such as the formula of permutation and combination, arithmetic progression's summation formula, the calculation method of slope and so on.
3. The idea is not clear, especially the idea of making problem data adequacy data.
4. The calculation is sloppy or the pace of doing the questions is too slow. Candidates should determine the focus and order of review according to their own problems.
Second, the preparation skills
1. Make full use of the existing information according to the problem.
For candidates who are not good at mathematics or are not familiar with mathematical terms, you can start with OG. OG is the official review material. When doing OG math problems for the first time, candidates can be fully familiar with the ideas of different questions, sort out the professional math terms and knowledge points involved, be familiar with long and difficult sentences, and be able to read the questions quickly and extract key information from them.
After the completion of OG, a certain foundation has been laid. At this point, candidates can practice the GWD math set and prepare for the math model exam.
When practicing the set of questions, the best way for candidates is to answer the questions within a limited time and try to complete them within the specified time. When doing a set of questions, we should further strengthen our familiarity with the questions and grasp the rhythm and skills of doing them.
Of course, candidates can also check the mathematical machine classics of the month before the exam, but the mathematical machine classics are only a supplement to a certain extent, which plays a icing on the cake. It is most important for candidates to lay a good foundation and enhance their own strength.
Attention to detail.
Many candidates felt good about themselves in the exam, but failed to get the expected high score. Maybe it's not that the math foundation is unqualified, it's just a matter of detail.
GMAT mathematics not only examines whether candidates have mastered basic mathematical concepts and calculations, but also examines the rigor and reasoning ability of candidates. Therefore, candidates must pay attention to the following points when doing the questions:
(1) Examine the questions carefully.
When doing the problem, pay attention to whether there are any key conditions missing. In addition, when you finish the question, you must confirm that the answer is really the answer required by the question.
(2) Pay attention to symbols and units.
The unit appearing in the question may be m, but the unit appearing in the option may be km; The unit that appears in the question may be hours, and the unit that appears in the option may be minutes; The unit in the question may be a number, but there is a% symbol in the option, so you should pay attention not only to whether the number corresponds, but also to whether the unit is unified.
(3) Make full use of skills to solve problems quickly.
When the examination time is tight, candidates can try to solve problems by algebraic eigenvalue method, which can improve efficiency and save time.
