ABOUT THE AUTHOR

Issa Niang is a first generation Afro-European, born and raised in Paris, France. His parents immigrated from Senegal to provide a better life for their children. He has held several leadership positions in the US, the UK, South Africa, Senegal, and France and has shown a track record of consistent excellence throughout his career.

His experience is complemented by an education that includes a Master’s Degree in Telecommunication Engineering, a Master of Science in Management and Organization, and a Graduate Degree in Business Administration, all earned from prestigious universities.

He discovered the GMAT in 2009 while he was living and working in the United States. After intense preparation, he managed to score a verified 780 in his first th attempt, placing him in the 99 percentile on both the quantitative and verbal sections. To contextualize this, over the past three years, less than 1 percent of the 800,000 test takers in the world have scored higher. Since then, he has helped many students around the world surpass their own goals and perform better than they ever thought possible.

The GMAT is unlike any other exam. It is not a test of knowledge; instead it evaluates how well you think, how you analyze, evaluate, and solve a problem. Consequently, the memorization of facts and figures can only produce limited results. Real success requires a focus on more sophisticated methods and an overall shift in how one approaches a problem.

Issa has decided to share his experiences by developing techniques and strategies useful for native and non-native English speakers alike to reconfigure their way of thinking and ace the GMAT. His experience has extended into the production of GMAT content and the creation of questions and detailed explanations for well-known GMAT test prep companies, and as a result he has become very familiar with the subtleties of the exam.

If your goal is to gain entry into a prestigious business school, this guide is for you. Where other test prep materials provide unnecessary fluff, this guide has cut the excess to provide only what is necessary to achieve success on the GMAT.

Three factors motivated its creation: • Developing a foundational understanding of the tested concepts from the ground up—everything relevant to the GMAT is included. • Building confidence by familiarizing students with all concepts tested and the best strategies and tactics for approaching each question type. • Focusing on the most important components necessary for maximal success on the GMAT.

Here you will find, in addition to this guide, many free resources, including: practice tests, e-books, articles, tips, strategies and admission advice, a list of recommended study material, a pre-review program, and a comprehensive list of official GMAT questions categorized by topic for a more focused practice.

WHAT IS THE GMAT?

What you should know…

The Graduate Management Admission Test (GMAT) uses a computer adaptive system to rank the test taker’s ability to juggle time constraints while analyzing arguments, solving math problems, and examining logic. The GMAT contains four sections that evaluate problem solving and critical thinking ability.

1) Analytical Writing Assessment (30 min.) This section features a single argument that must be deconstructed and argued for or against. It is vital that the analysis is written in a clear and thoughtful manner. Critical reasoning skills should always be applied to the Analytical Writing Assessment section.

2) Integrated Reasoning (30 min.) The newest section of the GMAT features graphs, tables, and charts that simultaneously challenge mathematical knowledge and reading comprehension. The structure of the question varies depending on what is being asked. Always work toward understanding rather than simply memorizing. Please check out my website www.alexanderprep.com; you will find free ebooks that explain in detail how to handle both preliminarily sections.

3) Quantitative (75 min.) This section tests mathematical skills and comprehension and is split into two question types: Problem Solving This type of question covers all forms of basic math, from basic algebra to geometric equations and statistics. These questions always require a definitive solution. Advanced mathematics, such as trigonometry and calculus, are not tested. Data Sufficiency This type of problem always features a question, such asthe sum of x and y is 10, and is followed by two pieces of related evidence. The goal is to determine if the statement is sufficient to prove the question. Even if it is tempting, do not use your gut to solve Data Sufficiency questions.

4) Verbal (75 min.) This section tests detail analysis, logic, and comprehension. Critical Reasoning These questions revolve around understanding an argument and identifying assumptions in order to weaken or strengthen the conclusion. Unlike Reading Comprehension passages, every word is important in a Critical Reasoning argument. Sentence Correction This question type tests the ability to recognize and correct statements that are ambiguous, illogical, or superfluous. Punctuation and vocabulary are never tested on sentence correction. Reading Comprehension Features passages that are structured to determine one’s ability to relate details, recognize conclusions, and describe tone. No information outside of the passage is ever necessary to correctly answer a question.

Facts and Tips • The GMAT is scored on a curve that is based on data collected during the previous three years. Verbal and quantitative sections are scored separately from 0 to 51. They are then combined, using an algorithm, into a final score between 200 and 800 points. Integrated Reasoning is scored on a scale of 1-8, while Analytical Writing Assessment is scored on a 1-6 scale. • For many business schools, the GMAT score is considered the only objective report of an applicant’s skill and knowledge, and plays a large role in getting accepted. • All scores, except the Analytical Writing Assessment, can be seen immediately upon finishing the exam. The full report is later delivered via email. • The Computer-Adaptive Test attempts to accurately measure a person’s understanding of the material by asking questions varying in level of difficulty. • The Item Characteristic Curve can make up approximately 10-25 percent of the verbal and quantitative questions. These are trial questions that have not yet been assigned a difficulty and do not count toward the final score. • The algorithm the GMAT uses has not been released publically. • The GMAT often penalizes for skipping a question. It is better to guess than to leave a question blank. Smart Guess, or an educated guess, increases the chance of landing on the correct answer by eliminating ones you know to be wrong. • Time management is a key factor of success on GMAT.

SUBJECT VERB AGREEMENT

What you should know…

All verbs must match the subjects in either singular or plural form. It may look simple; however, you must understand the rules within that framework.

1) Either … or … / Neither … nor … Rule:The verb always matches the nearest subject. 2) Compound subject Rule:A plural verb always follows a compound subject.

3) Additive phrases Rule:Understand the difference between a compound subject and an additive phrase. Similar to a modifier, an additive is always ignored. Common additive phrasing:with the help of, together with, in addition to.

4) Indefinite pronouns Rule:Singular verbs always follow indefinite pronouns. Common indefinite pronouns:anybody, anyone, anything, each, everything, nothing, no one, something…

5) Quantity words Rule:Quantity words modify nouns. They tell how many nouns are involved. Common quantity words:one, two, three, etc., some, many, all, several.

Example 1: Either a tree or flowersareplanted in the garden. Either flowers or a treeisplanted in the garden. Example 2: PaulandDenisedancetogether. Example 3: Noah, together with his father,ownsa bar. Example 4: Everybodygoes. Example 5: Anumber of inquiriesweresubmitted.
