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.


Next blog- I have ample time, how can i improve?...

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.
