GRE Review

WHat is it? Two sections that are 35 minutes in length 20 questions in each section There are 4 areas of math represented Arithmetic, Algebra, Geometry, Data Analysis 5 types of questions Quantitative Comparison (A is greater, B is greater, Equal, Can’t determine the relationship) Multiple Choice - 1 answer Multiple Choice - More than 1 answer Numeric Entry Data Interpretation Sets - Questions based on the same data presented in tables, graphs or other displays of data

Tips and Tricks MC - Instead of always “plugging in”, it may be faster to cover the answer choices and solve the question on your own and then compare. Can you estimate or approximate? Numeric Entry - Watch your rounding. Numeric entry - Pay attention to special symbols in front of boxes. All questions are weighted the same. Questions may be written in a way to confuse you. Answer choices are not random. Be on guard if the problem seems too easy.

Tips and Tricks Shapes are not drawn to scale. You do not have to reduce fractions, so don’t take the time. Numeric entry can be written as a fraction or decimal. Important information may be “hidden” in the middle of a sentence. Look for relationships. For example: The area of a triangle with the same perpendicular height and base as the length and width of a rectangle is exactly half of the area of that rectangle.

Tips and Tricks Make sure you know order of operations:

Tips and Tricks A little more than a third of the questions have been Quantitative Comparison (almost ⅖ or 40%). Don’t give yourself more than 2 minutes for each question. Quantitative Comparison: It only takes 1 example for something to not be true.

5 Strategies for solving Quantitative Comp Problems Add: for simplifying problems with 1 or more inequalities Cancel: for removing duplicate terms Sign: for plugging in positive and negative signs (+/-) in place of the variable(s) to help solve a problem Equate: for simplifying fractions that do not look alike and making them look alike (either in the numerator/top or denominator/bottom) Multiplying: for simplifying fractions through multiplication (to get rid of a denominator)

Tips for what I saw in problems 203² - 201² Difference of squares (203 + 201)(203-201) so that makes it (404)(2) = 808 This was much simpler. Quantity A: 641713 x 451222 Quantity B: 897189 x 318977 Divide the 2nd values by 1000000 which changes them to decimals and now you can use the calculator. As long as you divide each one equally, it will work.
