How to improve your GMAT score by 100 points - Part 1

Is there a short cut?. I get lots of queries -
" I want to improve my GMAT score by 100 points, I'm taking my exam in 2 weeks."

I'am sorry. If you are looking for a magic pill. I dont have a magic pill which can help you gain 100 points in 2-3 weeks.

If you have no other go and have only 2-3 weeks of preparation time left, then to gain 100+ pts, you need

1.to identify a category of question where you are consistently going wrong.
 say. "weakening the argument" type of question in CR. Study around 100 questions of the same category. Try decoding a generic strategy(a logical approach). This will help you to arrive at an answer using logic.

2. to manage your time effectively in the test. 
The adaptive test penalizes those who make mistakes early in the test( 1st question to the 15th  question) more than those who make mistakes later in the test. So that means you need to devote maximum time to the first few questions and minimum time to the later.

3. to get proper sleep the previous day of the test. 
Adequate rest is required to calm a tensed brain.

4.to manage stress effectively.
 You got a tough question in the test. You have eliminated 3 options. You have two options left. You are not sure which one to mark. You make a guess. You mark one. The next question turns out to be a sitter. You have a weird feeling in your stomach. The previous question may be wrong.
Don't worry!. The adaptive test penalizes GMAT takers who make successive errors ( question 1-correct, question 2-wrong, question 3-wrong, question 4-correct, question 5- wrong) more than those who make stand-alone errors( question 1-correct, question 2-wrong, question 3-correct, question 4- wrong, question 5- correct).

I have seen a handful of cases where GMAT test takers have improved their score by 100+ points but then again they had a specific error which could be corrected.

If you have no idea what is wrong with your performance then I would suggest that you mail me your queries and together we may be able to spot your Achilles heel.

GMAT sentence correction: Think beyond grammar

Fine, you know the GMAT SC jargon – tense error, pronoun error, subject verb disagreement. Good. Useful. But you must think beyond grammar to do justice to the range SC questions.

One of such errors is ambiguity. That is something is not clear. To make clear the meaning conveyed. So keep track of meaning  also while checking a sentence for errors.
Illustration  - real GMAT questions

1. Incorrect: In mammals, a lifetime’s supply of egg cells is produced during fetal development and remain dormant until maturity.

Here remain dormant is ambiguously used; one may ask what remain egg cells or development? In such cases, we need to repeat the word, cells, since these remain dormant until maturity.  The verb is agrees with the singular sub lifetime’s supply.

Correct … is produced during fetal development and the cells remain dormant until maturity.

2. In 1869, anxious to balance its population of 8,000 men and 2,000 women, the Wyoming legislature extended voting rights to women in Wyoming.

A. its population of 8,000 men and 2,000 women, the Wyoming legislature
B. their population of 8,000 men and 2,000 women, the Wyoming’s legislature
C. the state’s population of 8,000 men and 2,000 women, the Wyoming legislature
D. a state population of 8,000 men and 2,000 women, the legislature in Wyoming
E. its population of 8,000 men with 2,000 women, the Wyoming’s legislature

So since you know that singular pronouns agree with singular nouns, its agrees with Wyoming legislature. But grammar alone wont rescue us here.

Look at the meaning, can Wyoming legislature have population?  No the population belongs to the state, C is clear and exact. D, would mean any state’s population, not necessarily Wyoming’s.

Moral of the story
Attention to detail…is very important..keep looking out for similar errors; match grammar with meaning.

The big 50 point jump in the GMAT

Are you aspiring for a 700 in the GMAT and trying to figure out why your score is stuck at 650 and not hitting the 700 mark?

Here are potential reasons.

Firstly, are you ready for higher order reasoning and problem solving?  Find out, how consistently you have performed in data sufficiency questions, inference questions in reading comprehension and weaken/strengthen questions in critical reasoning( assuming  you worked out Official guide questions)

Secondly, while taking the computer based tests, did you fall short of time and guessed more than 5 question in either/both QA and VA section. If so penalty and poor pacing and time management is the issue.

Thirdly, your concentration wears of while you are working on the last part of the Verbal Ability section. Build stamina, slowly and steadily by taking many 4hrs tests.

To raise your score from 650 to 700, let’s say a re-taker do spend 30 days reworking on concepts, practicing with hundreds of tougher questions and analyse these questions to improve your performance.

GMAT critical reasoning - Bold face arguments

Standard arguments comprises a set of supporting statements followed by a conclusion.

A bold face arguments is more complex

GMAT critical reasoning tips- Bold face arguments

GMAT bold face arguments

Take each statement independently and see how it is related to the entire argument, including the other bold face.
Do not take only the relationship between the statements in bold.

GMAT verbal tips ( critical reasoning )

Inference is what follow the given statements, what must be true

Assumptions are what must precede the conclusion; what may have to be true.

If A is greater than B and B greater than C and B greater than D

Inference---B is lesser than A

Assumption----C may be lesser than D

GMAT verbal tips in a capsule ( sentence correction )-5

The pronoun should match the nouns, but that’s not sufficient.

Wrong: In1869, anxious to balance its population, the Wyoming legislature extended voting rights to women.
The pronoun ‘its’ agrees with the singular ‘Wyoming legislature’, but can legislature have a population.

Correct: In1869, anxious to balance the state’s population, the Wyoming legislature extended voting rights to women.

Attention to detail is what you should develop.
And do not forget to check the meaning of sentence.
