Short GRE reading comprehension passages - How do I identify the answer quickly?

 Is it possible to get all the GRE short passages questions correct?

 

Yes, it is possible to get all of the questions correct in the GRE.

I have tutored students since 2008. Some of them get all the questions correct. They also get the questions correct in less than a minute.

 

So what strategy did they use?

Almost all of them practice diagramming.

I teach students to diagram math problems as well.

 

Diagramming helps students analyse the question better. Students can

  • break down a complex problem
  • identify the essential information
  • eliminate the unnecessary data

Lets try this question


You are asked to identify the assumption

Spend 1 minute reading the paragraph

Now what sort of diagram will you draw for this question???

I teach students to draw diagram like this

 To identify the assumption, you have to focus on the conclusion and the reason why the scientist makes the conclusion.

 The conclusion - 

great apes have a capacity for self-awareness unique among nonhuman species.

So I will draw a circle and write capacity for self awareness..

 

Now whats the reason? Why did the scientist say this?


Reason:

animals recognize the reflection as an image of self -mirror self-recognition (MSR)

This i will represent as another circle.

 

 In the middle I  will put a black box.. In that box.. you have to put each answer option and check if the answer option gives additional information which can lead to the conclusion..

  

In this question only Option B gives a valid reason

 

the scientist assumes that if animal doesn't have capacity for MSR, then it doesn't have the capacity for self awareness.  Only then we can say great apes have a capacity for self-awareness unique among nonhuman species. If we are given that they have capacity for self awareness, then conclusion fails.

 Other options don't give a valid reason.

 You can use diagramming to break down any problem.

 

Happy learning.

How to study for GRE reading comprehension


Reading passages are drawn from many different disciplines and sources - the physical sciences, biological sciences, social sciences, arts and humanities and everyday topics and are based on material found in books and periodicals, both academic and nonacademic. All the questions can be answered on the basis of the information provided in the passage.

The test contains 12 to 15 passages, the majority of which are one paragraph in length and only one or two of which are several paragraphs long. 


Each reading comprehension question is based on a passage that may range in length from one paragraph to several paragraphs. 

One important skill you have to develop, to master this section, is critical reading.

so ,what is critical reading?

Critical reading means the reader applies certain

  • Process
  • Models
  • Questions
  • Theories

which results in enhanced clarity and comprehension.

 Generally students merely “skim” a passage. i.e the reader superficially reads the text, without noticing the

  • tone
  • organization
  • logical consistency
  • of the passage.

 

"Skimming" doesnt help much in GRE, as questions are mostly inference based questions.

 Critical reading help you tackle inference based questions easily.

 So, what does it take to be a critical reader? Here are few ways to build this skills

 

1. Read slowly

During the preparation phase, you should spend 20 to 30 mins on a passage. Only when you read slowly you will notice the 

  • tone
  • organization
  • logical consistency

of a passage.

 Do not worry about speed.at this stage of your preparation

When you master this reading style, your speed improves. Albeit gradually.

 While attempting the GRE, you should attempt to read and answer the questions in 6 to 8 mins.

 Does this sound intimidating?

 Feel free to contact me… we can chalk out a plan. I usually conduct reading aloud sessions with students. In that way they understand how my mind works. and how to read.

2. Use the dictionary

During GRE preparation, use a dictionary to understand words.

 Keep in mind, the meaning of the word, changes in context. 

 So you have to very careful while reading the passage.

 I usually give students a list of commonly tested words in the GRE

 

3. Make notes.

Jot down notes. Summarize ideas.

 When you read a line, see if it is related to the previous line or paragraph.. 

  1. Is it an explanation?
  2. Is it contrasting the information given earlier
  3. Is it supporting the information?

….

Note down the main ideas in a paragraph. 

  • Is the author making a claim?
  • Is he giving supporting reasons to the claim?
  • Also note the tone of the opinions..

 

is it mildly supporting or overtly supporting or moderately supporting or vociferously supporting?

 Note the degree - mildly/overtly/moderately/vociferously….

I will show you how to do this in another blog post..

  

4. Make a passage map.

Make a rough passage map from memory: test what you can recall from your reading of the text

 Make headings of the main ideas and note supporting evidence in dot points.

Include your evaluation: the strengths and weaknesses.

Identify gaps.

While answering questions.. refer your map.. go to that particular paragraph and reread those lines and then you can arrive at the answer.

 

5. Practice..practice

Practice makes perfect.

 I would recommend reading upto 150 GRE passages..

 Critical reading takes time to master..

 On an average students take 1.5 months to see progress in this section

   Keep in mind........

 Critical reading involves using logical and rhetorical skills. Identifying the author's thesis is a good place to start, but to grasp how the author intends to support it is a difficult task.

 More often than not an author will make a claim (most commonly in the form of the thesis) and support it in the body of the text. The support for the author's claim is in the evidence provided to suggest that the author's intended argument is sound, or reasonably acceptable.

 What ties these two together is a series of logical links that convinces the reader of the coherence of the author's argument: this is the warrant. If the author's premise is not supportable, a critical reading will uncover the lapses in the text that show it to be unsound.

 

Happy learning...

The classes for the revised GRE, are delivered in two stages

(i)Concepts and reasoning     (ii). Higher order questions

·         Context – based word building

Given the reasoning – based test design of the GRE, language building–words, idioms and sentence formation – is done in real contexts

·         Unique approaches to text completion  and reading completion and reading comprehension questions

·         Progress assessment

Regular progress tests – word tests, concept tests and mock tests – conducted in order to gauge your performance levels and to plan special lessons.

·         Faculty support

Continuous faculty support –individual and group – during the entire period of 

preparation

GRE math thinking skills 1

GRE tests your logical skills as well as your knowledge of math concepts.  To score high, you need to remember various formulas, theorems. Also you need to master critical problem-solving skills.

 I am going to take you through one problem-solving skill –

 Problem analysis with a diagram

Take this problem .

If you follow approach 1.

 You will use many formulas and theorems. You will get an answer, but it will take more time.

 If you follow approach 2.

You will minimize the number of formulas used. You will use your logical skills and reduce complex computation. You will solve questions faster.

In GRE time-taken per question is the key. If you solve questions in less than 30 seconds, then you will have more time in the bank to solve harder questions. You will also be able to complete the section in the allotted time.

Can logic be taught?

Yes!  Logic can be taught. If the tutor teaches you reasoning skills and demonstrates those skills on a wide range of problems, your thinking will get re-oriented. You will be able to solve questions using more than one approach.

 I feel Logic is best taught in a tutor-driven class, not through generic videos

Now let us understand both the approaches.

Approach 1

This approach involves formulae/theorem...

Area of square ABCD = side2

Side = 8. Hence area =64

F and E are midpoints of the respective sides. AB=AD=8

 Hence AF=FB=4 and AE=ED=4

 Triangle AEF, Triangle BFC and Triangle EDC are right angled triangles. Hence we can use Pythagoras theorem

This approach was time consuming. Also, This approach involves lots of calculation.

Approach 2 - faster approach

 

When you encounter geometry problems, look at the picture for few seconds.

Can you observe a square and 4 triangles?

Spend time observing the pictures and look for clues.

The area of shaded portion is equal to the area of the square – (sum of the area of the 3 triangles).

This approach requires you to know the area of the triangle = 0.5 x base x height.

Now let’s analyze the figure. F and E are the midpoints

 The sides of the square are 8

 Area of triangle AEF = 0.5x4x4 = 8

 Area of triangle EDC = 0.5x4x8 = 16

 Area of triangle FBC = 0.5x8x4 = 16

 Area of square =64

 Area of shaded region = 64- 16-16-8 =24

 This approach is far easier and involves less calculation.

 So always use logic to arrive at answers faster

How do we conquer the fear of GRE math?

 


Let start with a show of hands

 How many of us go blank when we see a math sum?

I can see that most of you are raising your hands, the others must be one of lucky 2%.


Now the big question.

Why some of us go blank and others seem to have the knack of solving math sums?

 

Well you can blame it on your mathematics teacher @ school or on your genes. But nevertheless while preparing for GRE or in fact while doing an Graduate course, you will encounter lot of math.

I can hear lots of groans. :-)

 

Few years back I read this book ‘How to solve it’ by George Polya. I modified my teaching style from just teaching question answers, question answers, question answers, question answers……to question logic answers, question logic answers, question logic answers…..

 

I found that I could tutor a person to achieve 160 within few weeks as instead of few months. Wow!! The best part of it I could see that students are able to solve math problems independently without me intervening.

 

In the book, Polya gives a detailed step by step process on how to approach math problems in general

 

I will modify the process and present it to you in context with GRE math

Keep these steps in mind when you approach a math problem in the future.

 

Step 1: Understanding the problem

Answer the following questions first

1.     Do you understand all the words used in stating the problem?

2.     What are you asked to find or show?

3.     Can you think of a picture or diagram that might help you understand the problem?

4.     Is there enough information to find the solution?

5.     What information, if any, is missing?

The answer to these questions will channelize your thinking towards the answer.

 

Step 2: Devise a plan

What will be the best approach to address the problem?

Approaches can only be devised. If a tutor explains a sum to you, then you will be able to understand only that problem. But when you encounter a new problem, you will go blank again.

Ideally when you encounter a new problem, you will have to use the existing ideas plus any new ideas you can conjure up. These process are mostly done mentally and involve little computation/calculation.

 

To get an idea, do any/all of the following.

1.     Make a systematic list/table

2.     Write an equation

3.     Consider special cases

4.     Use direct reasoning- for example If A>B and B>C then A>C.

5.     Use indirect reasoning.-Think of an earlier sum where you encountered a similar problem

6.     Look for a pattern

7.     Draw a picture

8.     Solve a simpler problem- break the problem into small parts and solve each part.

9.     Use a model- Make a general assumption and solve by guessing.

10. Work backwards. –work with answer options

Now that you have got an idea. Put pen on paper and solve to get an answer

 

Stage 3: Carry out the plan

 

Solve the problem with great care and patience

Discard the plan if it does not work and devise a new plan

Record what you have done to avoid repetitive work – For future use.

While attempting Data sufficiency questions, it is imperative you check your results. So

 

 

Stage 4: Looking back or checking

Have you addressed the problem?

Is your answer reasonable?

Can the method applied to other similar problems?

Is It consistent.

Now go ahead and repeat this thought process on different math problem and the next time when you see a math problem you will not go blank.

GRE Reading comprehension cues



Reading comprehension questions appear in the verbal section of the GRE exam. 


Because the Verbal section includes content from a variety of topics, you may be generally familiar with some of the material; however, neither the passages nor the questions assume knowledge of the topics discussed.


Typical reading comprehension questions you get in GRE.

1. The main idea or central theme of the passage

2. Information specifically mentioned in the passage (mostly line numbered)

3. Information implied in the passage

4. The tone, intent or mood of the passage

5. The author’s point of view that’s projected through the article

6. What could have logically preceded or followed the passage

7. The scope of the passage

8. What is true or untrue of the passage

9. What is / are the applications of the ideas


Here are some cues to keep in mind, when you read the passage.

1. Summarize each para in your own words

While reading a passage make a mental map; what each of the paragraphs deals with, the author’s intent…

 Read the passage and form a mental summary

Sample:

The problem is the problem of success itself. Earlier Brazil was a food deficit country, now it is a food surplus one. With surplus production of food have come the problems of storage and in turn the problem of capital being tied up in food grains. The solution that everybody seems to talk about is diversification - into fruits, flowers, fisheries and animal husbandry. This, of course, is easier said than done. First, the farmer has to be convinced of the need to market his produce, which cannot be done without providing him infrastructural support - roads and cold chain. Then there must be someone to do the marketing. After all,even the most progressive farmer has to be assured of a market and of returns on his investment. Of course physical infrastructure is not everything. Knowledge infrastructure - how to deal with perishable produce and where to take it - is also important.

Summary: Diversification of crops, as solution to problems arising from food surplus, can be successfully implemented only when farmers are provided with physical and knowledge infrastructure.

 

The Summary usually comprises the main point of the passage and the different views

  

2. Notice opinions

When you read the passage, notice the different points of view.

You will get questions based on person A’s/B’s… opinion or Authors opinion..

Sample:

“Initially the Vinaver theory that Malory’s eight romances, once thought to be fundamentally unified, were in fact eight independent works produced both a sense of relief and an unpleasant shock.”

There are three points of view in the line above

1. Vinaver’s view – There are 8 books

2. Somebody view– The books are unified

3. Authors view – the books produced both a sense of relief and a shock


Each paragraph will have many opinion/counter opinions.. Identify all of them. 

 

3. Notice thought reversals- but/however..

These words indicate a change in opinions/views…

Positive view to a negative view.. to a positive view…

 Sample:

“ It might seem that certain traits would clearly define a species as a keystone species; for example, Pisaster ochraceus is often a…………………. But such predation on a …………………………………… roles. Moreover, ……………………………and at certain sites sand burial is responsible for eliminating mussels.”

Words like But/Moreover.. indicate thought reversals.

 

4. Skim through descriptive data

Some passages have illustrative data.

Skims through illustrative matter and scan through meaty points

 

Sample

 “There are times when the night sky glows with bands of color. The bands may begin as cloud shapes and then spread into a great arc across the entire sky. They may fall in folds like a curtain drawn across the heavens. The lights usually grow brighter, then suddenly dim. During this time the sky glows with pale yellow, pink, green, violet, blue, and red. These lights are called the Aurora Borealis. Some people call them the Northern Lights. Scientists have been watching them for hundreds of years. They are not quite sure what causes them. In ancient times people were afraid of the Lights. They imagined that they saw fiery dragons in the sky. Some even concluded that the heavens were on fire.”

 

Descriptive data:  “There………….. violet, blue and red”

These line talk about the shapes,colours, sizes..


You need to quickly skim these statements and get the gist of the paragraph as a whole. When you observe an opinion/claim….. read  the statements intently.

 

5. Make a mental map of the entire passage to identify the layout (example para 1:claim, para 2: evidence 1,  para 3: evidence 3...)

 

 Read and map the passage

While reading segregate the meaty statements from purely illustrative matter.

 

Sample:

“Studies serve for delight, for ornament, and for ability. Their chief use for delight is in the private and retiring, for ornament is in discourse, and for ability is in judgment and disposition of business. Reading  and pursuing knowledge allow us to do three things: entertain ourselves in private, adorn or embellish our speech and increase our ability to, for example, make better judgments and decisions in conducting our business. For expert men can execute and perhaps judge of particulars, one by one, but the general counsels, and the plots and marshalling of affairs come best from those that are learned.

 Experts those who excel at or specialize in one thing, are good at handling particular problems within their area of expertise, but the larger issues of life are handled best by those who have studied more widely, who are more learned. To spend too much time in studies is sloth; to use them too much for ornament is affectation; to make judgments wholly by their rules is the humor of a scholar. Of course spending too much time reading is

lazinessreferring too much to our reading, dropping quotes everywhere, for example, is just showing off; and reacting to life according to the rules we’ve read is the characteristic of a scholar, some one who spends too much time in school, someone who doesn’t get out much into the real world" 

 The statements in bold are the main points/opinions/examples…These should be noted.  Also make a gist of the passage:

 Gist of the passage

The passage is about the benefits of reading- for delight, for communication and for better decision making. However, too much reliance on reading is acceptable, nor is using knowledge at every context welcome.



These are some of the reading cues to keep in mind while reading the passage.
