GRE Preparation with Quant, Verbal, Reasoning and online CBT Mock Tests

·         Graduate Record Examination or GRE is a standardized test that is an admission requirement for many graduate schools mainly in the United States and Canada.

·         ETS creates and administers this test worldwide.

·         It is usually computer-based test administered by top quality qualified testing centers. The paper-based GRE test is offered in those regions where computer-based testing is not available. In India, only computer-based test is offered.

·         The GRE test is only one of the several factors which graduate schools look at to decide the selection of a candidate. A high score alone does not convert to an admission offer. But the test can be looked upon as the first major hurdle to be cleared in the process of getting admission into a graduate school.

·         The Graduate Record Examination measures verbal, mathematical and analytical writing skills. There is more emphasis on your ability to understand what you've read and how you apply your reasoning and less reliance on vocabulary out of context.

The GRE revised General Test features question types that closely reflect the kind of thinking you'll do in graduate or business school.

• Verbal Reasoning — Measures your ability to analyze and evaluate written material and synthesize information obtained from it, analyze relationships among component parts of sentences and recognize relationships among words and concepts.
• Quantitative Reasoning — Measures problem-solving ability, focusing on basic concepts of arithmetic, algebra, geometry and data analysis.
• Analytical Writing — Measures critical thinking and analytical writing skills, specifically your ability to articulate and support complex ideas clearly and effectively.

Quantitative Comparison Questions for GRE Preparation

Strategies when the numbers are huge Let us try a tricky quantitative comparison question. Let’s see if you can get it in less than one minutes!

Quantity-A	Quantity-B
10^7	7^10

One way of solving this problem is to do the tedious calculations. However, doing so is a time-consuming, error-prone process, and though it may work, the GRE is not testing your ability to do laborious mathematics. Rather, it is testing the way you think, your logical approach to a complex problem. One useful approach is to approximate. For instance if we take 7^² we get 49. Notice 49 is very close to 50. So let’s say 7^² is equal to 50. Therefore (7^²)^² is equal to 50^² or 2500. 2500 can also be represented as 2.5 x 10^³. So when we take 2500^² or 7^⁸ we can convert 2500 into 2.5 x 10^3 and we have (2.5 x 10^³)^². Again, because we are approximating let’s round 2.5 down to 2. Now we have (2 x 10^³)^² = 4 x 10^⁶ = 7^⁸ . This figure is almost as large as 10^7. Since we are comparing 7^¹⁰ to 10^⁷ you can see that 7^¹⁰ will be much larger. Granted, this method still involves a decent amount of calculation. Another technique we can apply is pattern recognition. For example, we can use smaller numbers that adhere to the pattern above. So let’s compare 2^⁵ to 5^². Notice that I’ve kept a similar pattern to the original question: x^^y vs. y^^x. , where y = x + 3. In this case we get 2^⁵ = 32 and 5^² = 25. Notice that the number with the greater exponent is greater. We should try one more set of numbers just to be sure, 3^{^6} vs. 6^³. Notice that this time the difference between 3^⁶ and 6^³ is even greater than that between 2^⁵ and 5^². That is, the difference between x^{^y} and y^^x where y = x + 3 increases the larger the numbers we plug in. Therefore 7^¹⁰ will be much greater than 10^⁷. The answer is (B).
