10 must NOT DOs for GMAT math - Data sufficiency

10 must NOT DOs for GMAT math
the directions to Data sufficiency qns ( some tips below may require you to revisit these directions)This problem consists of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements are sufficient for answering the question. Using the data given in the statements plus your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of counterclockwise), you must indicate whether:

A statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked;
B statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked;
C BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient;
D EACH statement ALONE is sufficient to answer the question asked;
E statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.


Now here are some simple not dos
1.Assume that a given number is positive only. The numbers given can be zero, negative fractions or decimals.
i.e. sample
Main statement- is the modulus of X less than 3?
Sub statement 1- X(X+3) <0 Sub statement 2- X(X-3)>0
X can be zero, negative, fraction or decimal.

2. Assume that in a ‘Is...( refer main st in point 1 above ) question type, no is an invalid answer. ‘yes,’ can be a valid answer; no can be a valid answer. ‘sometimes yes and sometimes no’ are invalid.

3. Ignore minimum factors required( that can be gauged from the main st) to answer the qn, if either of the sub statements do not have the min factors, automatically the ans cannot be A or B.
Main st: Is X grater than Y?
Sub st 1. X is greater than Z
Sub st 2. Y is lower than Z
Here as per directions, the ans cannot be A or B.

4. Conclude based on the outcome, while substituting a number to arrive at the answer. Check the outcome while substituting varied numbers i.e. zero,+ve integer,-ve integer,+ve fraction and –ve fraction

5. Hurriedly Mark either A (or B) as the answer option when statement 1(or 2) yields an answer. Study statement 2(or 1)also . If this also leads to answer mark D, else mark A(or B)

6. Spent time deriving absolute values when approximation is sufficient in arriving at a decision.


7. Arriving at numerical values when the question requires only counting the occurrences.


8. Attempt a complex combinatronics problem by attempting to pick/select many objects at a time. pick/select one object at a time. This doesn’t change the final outcome.

9. Follow faulty logic.
i.e. A sample sum
Main statement- is the modulus of X less than 3?
Sub statement 1- X(X+3) <0 Sub statement 2- X(X-3)>0

Correct logic
Determine the range of numbers which satisfy the sub statements
Check whether these numbers satisfy the main statement.


Wrong logic
Determine the range of numbers which satisfy the main statement
Check whether these numbers satisfy the sub statements.

10. Ignoring additional information required to solve the problem
Sample problem
Main statement- A and B takes x and y days respectively to complete a work. How many days will A and B together take to complete it?
Sub statement 1 x=5
Sub statement 2 B alone takes twice as many days as A alone to complete the work

additional information on the efficiency of each person’s work per day is a factor needed. If A works at 50% efficiency, A will take 10 days to complete the work.

The new GMAT tests decision making

The GRE changed in 2011 with an overhaul in content and structure, making the test more reasoning based. Close on its heels comes the GMAT (admission test to majority of global MBA programs) change with the addition of a new section, aptly called ‘integrated reasoning’.
This new section replaces one of the essays and comprises 12 questions to be answered by analysing, synthesising, integrating and evaluating given data. The data to be integrated appear as maps, spreadsheets, codes, numbers, charts, texts, audios and graphs. Both multiple choice and highlighting statements or dragging data points constitute the questions.
The new section thus tests the candidates ability to examine and manage complex, multiple format data and draw conclusions from them. The integrated reasoning section will thus generate a measure of a candidate’s decision making skills.


The new GMAT from June 2012
Duration Raw score Final score
Argument essay (1 topic)
1 prompt
30 min
 Grade 0-6

Quant ability
37 qns
75 min
 0-60 raw score

Verbal ability
41 qns
75 min
0-60 raw score

Integrated reasoning*
12 qns
30 min
 To be announced in April 2012
*new addition

What doesn’t change?

The content, format and scoring of the verbal and quantitative sections remain unchanged; the argument essay also remains the same. The issue is replaced by the new section.
GMAT , in the present version itself is projected as a test that examines a range of skills that are prerequisites to participate in and benefit from a rigorous MBA curriculum. It already has a strong emphasis on reasoning. With the addition of the new integrated reasoning section, the test advances to another level of competence.


Test of decision making skills
The integrated reasoning section gives students an opportunity to demonstrate decision making skills- analysing, synthesising and evaluating data in different forms- numbers, flow charts and words to draw logical conclusions. In today's data-intense business space, effective decisions are taken by drawing intelligence and insights from various sources and information of various forms.
The introduction of such competency assessment in the business school intake stage presents a reasoned prognosis of one’s candidature to the world of competitive global business.


How to prepare
The verbal and quantitative sections are not changing in content patterns and scoring, thus test aspirants can continue to prepare for these as before. One has to familiarise oneself with the new section by practising on such problem sets as well as by reading graphs, maps and accompanying texts in business publications.
Since a good number of business schools take GRE score, instead of a GMAT score, applicants can research on colleges and find out which test to take. Some students may be more comfortable with the GRE test.

Test aspirants starting preparation post-March 2012 may have to take the new GMAT administered form June 2012. Good preparation will be the key to success.

Which business schools have produced the most entrepreneurs?

I got this information through a certain website though i could share it with you all...


Which business schools have produced the most entrepreneurs?
A recently published LinkedIn study examined the backgrounds of members who identify themselves as startup founders and came up with the leading schools for entrepreneurs.
The results dramatically differ from the two most-cited yet deeply flawed rankings of leading entrepreneurial programs by Princeton Review and U.S. News & World Report. By sifting through its more than 120 million member profiles, LinkedIn has produced the ideal “put up or shut up” analysis. It’s the kind of data that calls out schools that have made entrepreneurship a marketing or promotional vehicle vs. those that have produced actual startup entrepreneurs.

LinkedIn membership data shows these five schools produced the most startup founders:
Stanford,
Harvard,
MIT Sloan,
Berkeley’s Haas School, and
Dartmouth College’s Tuck School.

The next five are Wharton, Columbia, Babson, Virginia Darden, and the Johnson School at Cornell University.

Why the results are surprising
Babson, which has long been number one in both rankings, does no better than eighth place. Tuck, which fails to make the U.S. News list of 27 schools or the Princeton Review list of 25 schools, is firmly in the top five.
Columbia Business School, which doesn’t make the Princeton Review list and comes in at 19th on U.S. News, has the seventh largestnumber of startup founders in LinkedIn’s database. Chicago Booth, which is ranked second by Princeton Review, doesn’t make the LinkedIn list at all. Neither does Michigan, Brigham Young, or the University of Arizona, all schools in Princeton Review’s top five.
A side-by-side comparison (below) of the LinkedIn list with the two other rankings tells the story well. Seven of LinkedIn’s top ten schools don’t even warrant a mention in the Princeton Review ranking. LinkedIn’s number one school, Stanford, ranks a mere eighth on the Princeton Review list. Two of LinkedIn’s top ten schools don’t make the U.S. News list even though it rates 27 schools.

LinkedIn Rank & School U.S. News Rank Princeton Review
1. Stanford                         2                     8
2. Harvard Business School 4                    NR
3. MIT Sloan                         3                    NR
4. California-Berkeley (Haas) 6                   NR
5. Dartmouth (Tuck)               NR               NR
6. Pennsylvania (Wharton) 5                   NR
7. Columbia Business School 19                    NR

10. Cornell (Johnson)           NR                      NR

Of course, not every entrepreneur may have a LinkedIn profile and even those that do may not fall within the parameters of the professional network site’s methodology. LinkedIn counted members who identified themselves as founders or co-founders of U.S. companies created after 2000, with a LinkedIn company profile, and that currently has between two and 200 employees. LinkedIn excluded small law, consulting and real estate firms, as well as LLCs. Using these guidelines, LinkedIn came up with a pool of more than 13,000 entrepreneurs for its survey.

The LinkedIn ranking is not based on raw numbers, but rather on “how ‘over-represented’ those schools are among entrepreneurs,” according to Monica Rogati, a senior data scientist at LinkedIn who did the analysis. “This levels the playing field for small schools, as you have noticed but it makes it less surprising, which is why I wanted to mention it.”

This compares with U.S. News, which simply asks b-school deans and MBA directors, to rank schools on the basis of their entrepreneurship programs—even though they have no direct knowledge of those programs. Princeton Review, meantime, may as well pull its results out of a hat. Its methodology is so unclear and unspecific that it is hard to say exactly how the ranking is put together. It supposedly attempts to measure “academics and requirements,” “students and faculty,” and “outside the classroom.” (Our critique of the ranking was published last year.)

That’s why the new LinkedIn list has more gravitas–because it is based on real results—not what a few deans think about programs for which they no knowledge or some voodoo methodology by an organization that refuses to properly disclose how it comes up with a ranking.

GMAT CR tips

GMAT CR tip
be aware of the most common ways in which reasoning can go wrong. this will help spot them in CR arguments as well as
guard against these errors in your essay writing.
some of those ways are
- confusing cause and effect
- using unpresentative statistics
- employing faulty analogy
- drawing hasty generalisation
more of these you may get at our website- www.semanticslearning.com

GMAT sentence correction tips

GMAT sentence correction tip

check each sentence for semantics( meaning conveyed) and syntax( the grammatical structure and conformity).
syntax is altered to convey the meaning aptly, not the other way around.

in addition to these two, terseness is important- being economical with words
caution: if being terse, ie reducing words, lead to ambiguity, length is welcome.
here are two eg.

eg. 1.
ambiguous: Piaget noted that in children a repertoire of skills is acquired during preschool period and need further
strengthening through organized learning experienced at school.

what needs strengthening is ambiguous, so we need to repeat some words

Piaget noted that in children a repertoire of skills is acquired during preschool period and these skills need further
strengthening through organized learning experienced at school.


eg 2- a wordy sentence
The houses were mostly well built in construction, but the interior furnishing within the house left much
to be desired.
economical
the houses were mostly well- built, but the interiors left much to be desired.
