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 [...]

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 [...]

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 [...]

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 [...]

Your skills that you practice while studying for critical reasoning will help you immensely here. Every argument will have at least one flaw, probably several. You should think of the passage as if it was all true within itself and focus on how well the conclusion flows from the premises. Don’t question the facts. Question [...]

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 [...]

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 [...]
