GMAT Prep

The good news is that for most students, you will have covered the math you need for GMAT before you graduated high school.  In other words, it is not high level math.  The problem is translating the English word problem into numbers and mathematical functions/operations like +, - , x, / and =.   Then, write out the formula (mathematical sentence?) including the unknown as variables like x or y. Usually there are two of these that can be combined to give an answer.  Operations such as + or ‘plus’ could be written with the verbs add or mix.  - or ‘minus’ could be ‘take away’, ‘subtract’, ‘minus’, ‘remove’ or ‘reduce by’.  X or ‘times or multiply by’  could be ‘each’, ‘the product of’, or ‘per’ or ‘of’.  / or ‘divided by’ could be ‘divided equally’ or ‘shared between’.  = or ‘equals’ could be ‘is’, ‘totals’, ‘sums up to’, ‘combine to be’.   There are also words from math such as ‘random’, ‘integer’, and ‘range’.   Comparatives like ‘greater’ or ‘more than’ >  and ‘less’ or ‘fewer than’ < also can be translated into mathematical symbols.     With practice, you can recognize the key language in the questions and translate them to mathematical operations then build the formulas you need to solve the problem.    Try the following questions from one of the the official practice tests on the GMAT website.  Link to Google Drive document with this post and five sample questions: https://docs.google.com/document/d/1s6f3VEw7aymXzFsIOyER5Nn7e5-naGFucP9YAwOpw_s/edit?usp=sharing
