HOW THE COMPUTER-ADAPTIVE GMAT SECTIONS WORK

To understand how to beat the computer-adaptive sections (Math and Verbal) of the GMAT, you have to understand how they work.

 

Unlike paper-and-pencil standardized tests that begin with an easy question and then become progressively tougher, the computer-adaptive sections always begin by giving you a medium question. If you get it correct, the computer gives you a slightly harder question. If you get it wrong, the computer gives you a slightly easier question, and so on. The idea is that the computer will zero in on your exact level of ability very quickly, which allows you to answer fewer questions overall and allows the computer to make a more finely honed assessment of your abilities.

計算機自適應GMAT部分的工作方式

要了解如何擊敗GMAT的計算機自適應部分(數學和語言),您必須了解它們的工作原理。

 

與紙筆標準化測試從一個簡單的問題開始,然後變得越來越困難,計算機自適應部分始終以一個中等問題開始。 如果正確,計算機將向您提出一個稍微困難的問題。 如果弄錯了,計算機會給您一個稍微容易些的問題,依此類推。 這個想法是,計算機將很快將您的準確水平歸零,這使您總體上可以回答較少的問題,並使計算機對您的能力進行更精細的評估。

What You Will See on Your Screen

During the test itself, your screen will display the question you’re currently working on, with little circles next to the five answer choices. To answer the question, you use your mouse to click on the circle next to the answer choice you think is correct. Then you press a button at the bottom of the screen to verify that this is the answer you want to pick.

您在屏幕上看到的內容

在測試過程中,您的屏幕將顯示您當前正在處理的問題,在五個答案選項旁邊帶有小圓圈。 要回答該問題,請使用鼠標單擊您認為正確的答案選項旁邊的圓圈。 然後,按屏幕底部的按鈕,以確認這是您要選擇的答案。

What You Will Never See on Your Screen

What you will never see is the process by which the computer keeps track of your progress. When you start each adaptive section, the computer assumes that your score is average. So, your starting score for each section is around a 30. As you go through the test, the computer will keep revising its assessment of your score based on your responses.

 

Let’s watch the process in action. In the left-hand column on the next page, you’ll see what a hypothetical test-taker—let’s call her Jane—sees on her screen as she takes the test. In the right-hand column, we’ll show you how GMAC keeps track of how she’s doing. (We’ve simplified this example a bit in the interest of clarity.)

 

Note: The answer choices on the actual GMAT don’t have letters assigned to them. Instead, you select your response by clicking on an adjacent oval. For the sake of clarity and brevity, we’ll refer to the five answer choices as (A), (B), (C), (D), and (E).

屏幕上看不到的內容

您將永遠看不到的是計算機跟踪進度的過程。 當您開始每個自適應部分時,計算機會假定您的分數是平均水平。 因此,每個部分的起始分數約為30。通過測試時,計算機將根據您的回答不斷修改對分數的評估。

 

讓我們看看實際過程。 在下一頁的左列中,您會看到假設的考生-她叫她的簡-在參加考試時在屏幕上看到的內容。 在右側欄中,我們將向您展示GMAC如何跟踪她的表現。 (為了清楚起見,我們對這個示例進行了一些簡化。)

 

注意:實際GMAT上的答案選項沒有分配字母。 相反,您可以通過單擊相鄰的橢圓形來選擇響應。 為了簡潔明了,我們將五個答案選項稱為(A),(B),(C),(D)和(E)。

What Jane Doesn’t See:

When you start each adaptive section, the computer assumes that your score is average. So, your starting score for each section is around a 30. Jane gets the first question correct, (C), so her score goes up to a 35, and the computer selects a harder problem for her second question.

簡未看到的內容:

當您開始每個自適應部分時,計算機會假定您的分數是平均水平。 因此,每個部分的起始分數約為30。簡將第一個問題答對了(C),因此她的分數升至35,並且計算機為第二個問題選擇了較難的問題。

WHAT JANE SEES:

Hawks in a certain region depend heavily for their diet on a particular variety of field mouse. The killing of field mice by farmers will seriously endanger the survival of hawks in this region.

 

Which of the following, if true, casts the most doubt on the conclusion drawn above?

 

The number of mice killed by farmers has increased in recent years.

 

Farmers kill many other types of pests besides field mice without any adverse effect on hawks.

 

Hawks have been found in other areas besides this region.

 

Killing field mice leaves more food for the remaining mice, who have larger broods the following season.

 

Hawks are also endangered because of pollution and deforestation.

特定區域中的鷹在很大程度上依賴特定田鼠的飲食。 農民殺死田鼠將嚴重危害該地區鷹的生存。

 

以下哪項(如果為真)對以上得出的結論最懷疑?

 

近年來,被農民殺死的小鼠數量有所增加。

 

除田鼠外,農民還殺死了許多其他類型的害蟲,對鷹沒有任何不利影響。

 

在該地區以外的其他地區也發現了鷹。

 

殺死野外老鼠會給剩下的老鼠留下更多的食物,而這些老鼠在下個季節的繁殖力更大。

 

鷹也因為污染和森林砍伐而受到威脅。

WHAT JANE DOESN‘T SEE:

The computer happens to select a Critical Reasoning problem.

 

Oops. Jane gets the second question wrong (the correct answer is (D)), so her score goes down to a 32, and the computer gives her a slightly easier problem.

哎呀。 簡將第二個問題弄錯了(正確答案是(D)),所以她的分數降低到32,而計算機為她提供了一個稍微容易些的問題。

WHAT JANE DOESN‘T SEE:

Jane has no idea what the correct answer is on this third question, but she guesses (E) and gets it correct. Her score goes up to a 33.

簡未看到的內容:

簡不知道第三個問題的正確答案是什麼,但她猜(E)並得出正確答案。 她的分數上升到33。

You get the idea. At the very beginning of the section, your score moves up or down in larger increments than it does at the end, when GMAC believes it is merely refining whether you deserve, say, a 42 or a 43. The questions you will see on your test come from a huge pool of questions held in the computer in what the test-writers call “difficulty bins”—each bin with a different level of difficulty.

你明白了。 在本節的開始,您的分數會以比結尾時更大的幅度上下移動,這時GMAC認為,這只是在完善您是否值得,例如42或43。 測試來自計算機中存儲的大量問題,即測試編寫者稱之為“困難箱”的問題-每個箱的難度都不同。

The Experimental Questions

Unfortunately, approximately one-fourth of the questions in each adaptive section (Math and Verbal) won’t actually count toward your score; they are experimental questions being tested out on you. The difficulty of an experimental question does not depend on your answer to the previous question. You could get a question correct and then immediately see a fairly easy experimental question.

 

So, if you are answering mostly upper-medium questions and suddenly see a question that seems too easy, there are two possibilities: a) you are about to fall for a trap, or b) it’s an experimental question and really is easy. That means it can be very difficult for you to judge how you are doing on the section. Your best strategy is to simply try your best on every question.

 

Remembering that experimental questions are included throughout the adaptive sections can also help you use your time wisely. When you get stuck on a question—even one of the first 10 questions—remember that it might be experimental. Spending an inordinate amount of time on one question could cause you to rush and make silly mistakes later. Would you really want to do that if the question turned out to be experimental?

 

In those situations, eliminate as many answer choices as you can, guess, and move on to the next question.

實驗性問題

不幸的是,每個自適應部分(數學和口頭)中大約四分之一的問題實際上不會計入您的分數;他們是實驗性問題,正在對您進行測試。實驗性問題的難度並不取決於您對前一個問題的回答。您可以正確回答一個問題,然後立即看到一個相當簡單的實驗性問題。

 

因此,如果您回答的大多是中高級問題,而突然發現一個看起來似乎很簡單的問題,則有兩種可能性:a)您將要陷入困境,或者b)這是一個實驗性問題,確實很容易。這意味著您可能很難判斷自己在本節中的表現。最佳策略是在每個問題上都盡力而為。

 

記住自適應部分中包含實驗性問題,也可以幫助您明智地利用時間。當您陷入一個問題(甚至是前十個問題中的一個)時,請記住這可能是實驗性的。在一個問題上花費過多的時間可能會導致您倉促行事,並在以後犯下愚蠢的錯誤。如果問題是實驗性的,您真的要這樣做嗎?

 

在這種情況下,請盡可能少地選擇答案,猜測並繼續下一個問題。

What the Computer-Adaptive GMAT Uses to Calculate Your Score

The GMAT keeps a running tally of your score as it goes, based on the number of questions you get correct and their levels of difficulty—but there are two other important factors that can affect your score:

 

Early questions count more than later questions.

 

Questions you leave unanswered will lower your score.

計算機自適應GMAT用於計算分數的內容

GMAT會根據您得到的正確問題的數量及其難度來實時記錄您的分數,但是還有兩個重要的因素會影響您的分數:

 

較早的問題比較晚的問題更為重要。

 

您未回答的問題將降低您的分數。

Why Early Questions Count More Than Later Questions

At the beginning of the test, your score moves up or down in larger increments as the computer hones in on what will turn out to be your ultimate score. If you make a mistake early on, the computer will choose a much easier question, and it will take you awhile to work back to where you started from. Similarly, if you get an early problem correct, the computer will then give you a much harder question.

 

However, later in the test, a mistake is less costly—because the computer has decided your general place in the scoring ranks and is merely refining your exact score.

 

While it is not impossible to come back from behind, you can see that it is particularly important that you do well at the beginning of the test. Answering just a few questions correctly at the beginning will propel your interim score quite high.

為什麼早期的問題比後面的問題更重要

在測試開始時,隨著計算機逐漸提高最終分數,您的分數將以較大的幅度上下移動。 如果您在早期犯了一個錯誤,計算機將選擇一個容易得多的問題,這將需要您花費一些時間來重新開始。 同樣,如果您早日解決了問題,那麼計算機將向您提出更困難的問題。

 

但是,在測試的後期,由於計算機已經確定了您在得分排名中的一般位置,而只是在完善您的準確分數,因此錯誤的代價更低。

 

儘管從後面回來並不是沒有可能,但是您可以看到在測試開始時保持良好狀態尤為重要。 在開始時正確回答幾個問題將使您的期中成績很高。

Pace Yourself

Make sure that you get these early questions correct by starting slowly, checking your work on early problems, and then gradually picking up the pace so that you finish all the problems in the section.

 

Still, if you are running out of time at the end, it makes sense to spend a few moments guessing intelligently on the remaining questions using Process of Elimination (POE) rather than random guesses or (let’s hope it never comes to this) not answering at all. You will be pleased to know that it is possible to guess on several questions at the end and still end up with a 700.

 

On the next page, you’ll find our pacing advice for Math and Verbal. The charts will tell you how much time you should spend for each block of 10 questions based on a practice test score.

自己的步調

慢慢開始,檢查早期問題的工作,然後逐步加快步伐,以確保完成本節中的所有問題,以確保正確解決了這些早期問題。

 

不過,如果您最後沒時間了,那麼有必要花一些時間使用消除過程(POE)對剩餘的問題進行明智的猜測,而不是隨機猜測,或者(希望這永遠不會涉及到)不回答 完全沒有 您會很高興地知道,可以在最後猜幾個問題,但最終還是得到700分。

 

在下一頁上,您會找到有關Math和Verbal的節奏建議。 圖表將根據實踐考試分數告訴您,每10個問題塊應花費多少時間。

Know Your Bin

According to classic theory, average test-takers spend most of their time answering questions at their level of competency (which they get correct) and questions that are just above their level of competency (which they get wrong). In other words, most test-takers will see questions from only a few difficulty “bins.”

 

This means that to raise your score, you must learn to answer questions from the bins immediately above your current scoring level. At the back of this book, you will find a short diagnostic test to determine your current scoring level, as well as bins filled with questions at various scoring levels. When combined with a thorough review of the topics covered on the GMAT, this should put you well on your way to the score you’re looking for.

知道你的垃圾箱

根據經典理論,普通應試者會花費大部分時間來回答其能力水平上的問題(他們得到了正確的答案)和正好高於其能力水平上的問題(他們得到了錯誤)。 換句話說,大多數應試者僅會從幾個難度“箱”中看到問題。

 

這意味著要提高您的分數,您必須學會從緊鄰當前得分水平的垃圾箱中回答問題。 在本書的最後,您將找到簡短的診斷測試,以確定您當前的評分水平,以及在各個評分水平上充滿問題的垃圾箱。 與對GMAT涵蓋的主題進行徹底的審查相結合,可以使您輕鬆找到自己想要的分數。

Summary

The computer-adaptive sections of the GMAT always start you off with a medium question. If you get it correct, you get a harder question; if you get it wrong, you get an easier question. The test assigns you a score after each answer and quickly (in theory) hones in on your level of ability.

 

Mixed in with the questions that count toward your score will be experimental questions that do not count toward your score. The testing company is using you as an unpaid guinea pig to try out new questions. Approximately one-fourth of the questions in each of the adaptive sections are experimental.

 

Because the test is taken on a computer, you must answer each question to get to the next question—you can’t skip a question or come back to it later.

 

Because of the scoring algorithms, early questions count more than later questions—so check your work carefully at the beginning of the test.

 

The GMAT computer-adaptive sections select questions for you from “bins” of questions at different levels of ability. The Princeton Review method consists of finding your current bin level through diagnostic tests and then practicing questions from that bin, gradually moving to higher bins as you become more proficient.

概要

GMAT的計算機自適應部分始終會以中等問題開始您的學習。如果正確,則會遇到一個更棘手的問題。如果弄錯了,您會得到一個更簡單的問題。該測試會在每個答案後為您分配一個分數,並在理論上快速地提高您的能力水平。

 

與不計入分數的問題混合在一起的是實驗性問題。測試公司正使用您作為無償豚鼠來嘗試新問題。每個自適應部分中大約四分之一的問題是實驗性的。

 

由於測試是在計算機上進行的,因此您必須回答每個問題才能進入下一個問題-您不能跳過一個問題,也不能稍後再返回。

 

由於採用了評分算法,因此,較早的問題要比較早的問題更為重要-因此在測試開始時請仔細檢查您的工作。

 

GMAT計算機支持的部分從具有不同能力水平的問題“箱”中為您選擇問題。 Princeton Review方法包括通過診斷測試找到您當前的垃圾箱級別,然後練習該垃圾箱中的問題,並隨著您變得越來越熟練而逐漸移至更高的垃圾箱。
