GMAT數(shù)學高分小技巧2017
GMAT數(shù)學題目類型分為兩種，PS + DS。要想拿到51分滿分，一定要把握好考試技巧。下面是小編整理的幾個拿到GMAT數(shù)學高分的小技巧，希望對大家有用，更多消息請關注應屆畢業(yè)生網(wǎng)。
GMAT數(shù)學考試小技巧：
1.先花一定的時間熟悉數(shù)學術語。
2.花一點時間，做一定量的標題，領會一下GMAT數(shù)學的命題特征。
3.假如難題有一些艱難，這個階段用一些參考材料，學習一下前人的總結一下。當然，這個階段不要占用溫習中的大量時間。畢竟考試分數(shù)中的局部，并不是這些偏難怪題，偏題怪題對于GMAT數(shù)學考高分意義不大。
4.開端壓時間做數(shù)學練習，這一步是GMAT數(shù)學考高分的關鍵。
5.�？迹欢ㄒ旰玫刈鲆幌履７驴荚�，尋覓一下在考試現(xiàn)場的覺得。
GMAT數(shù)學考高分需要提示的幾個習慣：
1.不要用大意作為做錯標題的借口，一定要在思想層面去尋覓一下錯誤的緣由。
2.如果算出了答案但是少關注了一兩個條件，一定停下來好好想一想，這些看起來無關的條件和選項，能否是真的無關。
3.同一道標題當中，度量單位和可能是不一樣，一定要看分明，膽大心細是GMAT數(shù)學考高分的必備條件。
4.PS題中，不一定請求出詳細數(shù)值，假如能夠預算一下也能肯定答案的話，就只需求預算一下，畢竟是選擇題;DS題是不需求求解值的，也不要隨意去估量一個太過特殊的數(shù)值，招致判別失誤。這個是GMAT數(shù)學考高分需要權衡的。
5.有沒有想當然本人肯定的條件，而并不是出標題人給你的。比方說幾何圖形只是個草圖而已，而并不是準確的圖形。
以上就是幾個GMAT數(shù)學考試中常用的技巧，考生可在平時的復習中進行培養(yǎng)，以達到提高GMAT數(shù)學考試成績的目的。
數(shù)學練習題
If a square mirror has a 20-inch diagonal, what is the approximate perimeter of the mirror, in inches?
(A) 40
(B) 60
(C) 80
(D) 100
(E) 120
邏輯
A recent report determined that although only 3 percent of drivers on Maryland highways equipped their vehicles with radar detectors, 33 percent of all vehicles ticketed for exceeding the speed limit were equipped with them. Clearly, drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly than are drivers who do not.
The conclusion drawn above depends on which of the following assumptions?
(A) Drivers who equip their vehicles with radar detectors are less likely to be ticketed for exceeding the speed limit than are drivers who do not.
(B) Drivers who are ticketed for exceeding the speed limit are more likely to exceed the speed limit regularly than are drivers who are not ticketed.
(C) The number of vehicles that were ticketed for exceeding the speed limitwas greater than the number of vehicles that were equipped with radar detectors.
(D) Manyof the vehicles that were ticketed for exceeding the speed limitwere ticketed more than once in the time period covered by the report.
(E) Drivers on Maryland highways exceeded the speed limitmore often than did drivers on other state highways not covered in the report.
數(shù)學
答案：B
邏輯
A While this statement about being ticketed may be true, the conclusion pertains to the recurrentexceeding of the speed limit, so this statement is not relevant.
B Correct. This statement properly identifies the conclusion's necessary assumption about ticketed drivers' beingmore likely to drive in excess of the speed limit than nonticketed drivers.
C This statement is about the numberof vehicles ticketed, not about the regular habits of drivers, so it is not assumed for the conclusion.
D While this additional information could help support the conclusion, it is not a necessary
assumption in the conclusion because it isabout the particular example of the drivers in Maryland, not about drivers' habits in general.
E Learning that Maryland drivers are not representative ofother drivers undermines the conclusionabout all drivers, so it is clearlynot assumed.
The correct answer is B.
