## 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 key to GMAT speed and distance problems

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 [...]

## GMAT algebraic translation made easy

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 [...]

## What you need to know about GMAT Data Sufficiency

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 [...]

## What you need to know about GMAT Problem Solving

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 [...]
