GMAT Work and Rate Problems

Work and rate problems are very similar to speed and distance problems, because you have a rate multiplied by a unit of time, resulting in an overall accomplishment, (distance or work). Like speed and distance problems, work and rate problems won’t come in a simple form. You will need to manipulate the work equation to [...]

The most important equation to remember for distance problems is:             (Speed)*(Time)= Distance Usually, however, questions will not be presented to you so simply and you will have to manipulate this equation to find your answer. Take, for instance, this example: Train 1 leaves Kaohsiung at 12pm and heads directly to Taipei.   It travels at [...]

GMAT Probability Basics

Probability problems come up quite a bit on the GMAT, so it is important to understand them. The Probability of an event is:          # of Successful outcomes       # of Total possible outcomes Say, for instance we want to calculate the probability that you roll three on a six-sided die. The number of successful outcomes [...]

The two most important parts of successfully doing percent problems on the GMAT is to understand the language and to take the problem step by step. Percent Language The language of percentages is very specific and if you misread it, then you probably won’t get the answer right. For example, it’s important to understand how [...]

Quick GMAT Triangle Tricks

Triangles come up on the GMAT quite a bit. They can be quite complicated and difficult, but if you know the common patterns you can learn to navigate through these questions much more quickly. Common Right Triangles: There are several common right triangles that show up on the GMAT often. If you memorize these, you [...]

A lot of GMAT students have trouble with algebraic translation. This can be a huge detriment to someone’s score, because turning words into algebraic equations is a key component of many GMAT questions. However, it doesn’t have to be as difficult as it seems. The key to algebraic translation is to break everything down into [...]

Data Sufficiency is a little more complicated than problem solving.  In a data sufficiency problem, you are given some information and a question and you have to figure out IF the problem can be solved based on that information. Let’s look at an example with the same problem: Jeb and Carla start at opposite ends [...]

Of the total 37 questions on the quant section, you will see two different kinds: problem solving and data sufficiency.  You have probably seen problem solving type problems all throughout studying math in school.  These types of questions simply lay out a problem for you to solve and give you 5 answer choices from which [...]
