## GMAT Problem Solving strategy: test answer choices

One way to quickly answer questions when you are stumped is to try to test answer choices.  You are only given five, so sometimes this will get you to the correct answer faster than doing the work to multiply the problem out. You can rent DVDs at a local video store for 5.00 per movie [...]

## GMAT Data Sufficiency tip: flesh out the prompt

It is very important to tackle data sufficiency in a formulaic way.  There are too many options to keep them in your mind all at once, so its better to methodically eliminate things until you have only one option left. The first and most important step is to flesh out the prompt, so you can [...]

## GMAT Problem Solving Strategy: plug in numbers

Another strategy that might get you to the answer faster than simply doing the problem outright, is plugging in numbers. This might make it easier to visualize the problem and help you work through it faster.  If you are struggling with a GMAT problem and are having trouble visualizing the problem, try replacing the unknowns [...]

## GMAT AWA: How to structure your essay and budget your time

Structuring your essay Like any essay, you need an introduction and a conclusion.  You should start the introduction by restating the argument in some way and then by giving a broad, general statement about what is wrong with it.

## GMAT Problem Solving Strategy: estimation

If you are looking at a problem solving question, and thinking about tackling it in a long, roundabout way, then you are probably looking at it wrong.  The questions are written in such a way that it seems like there is only an extremely complicated way of doing things, but in reality there is always [...]

## GMAT Data Sufficiency Tip: test numbers strategically

Another good strategy for DS is to test numbers.  However, this strategy is not as effective if you don’t test the number strategically.  For example, if you have a problem that asks if is x positive and (I) says x2 < x testing only positive integers won’t tell you much about x.  For example, this [...]

## GMAT Data Sufficiency tip: compute (I) and (II) to completion

Just like it is important to flesh out your prompt, it is equally important to flesh out (I) and (II) in the context of the question.  Let’s look at another example: x=y+1  what is the value of xy? (I) x2 = y + 1 (II) x =  √ (y+1) The prompt is pretty straightforward.  We are [...]

## GMAT Data Sufficiency tip: pay attention to constraints

An important aspect to pay attention to with GMAT data sufficiency, is the constraints.  When talking about constraints, I mean more than just x>0, but also the ones that are not as obvious.  For example, if you are asked for a number of people, you know that it has to be an integer, because you can’t [...]
