What’s the difference between a real GMAT and a practice one? On the real GMAT, you’re finished after three and a half hours, give or take. But while you are preparing for the GMAT, finishing a practice test is much different than being finished with it. As I’ve written about before, practice tests are great assessment tools but not necessarily great learning tools. Practice tests tell you what you would likely score on the real GMAT if you answered 37 quant and 41 verbal questions with the same level of aptitude that you had on the questions you just saw. But if you want to see your GMAT score improve, you’re going to have to spend some time reviewing what you did, how you did it, and how you could do it better. To help you on that quest to get better, here are four kinds of questions that you can use to help improve your score.
1) Questions You Got Wrong
This one is the obvious one- if you want to get better at the GMAT, you need to find questions that you got wrong and learn how to get them right. But this isn’t as simple as finding an explanation online and memorizing it (although our forums are a great place to get many of your hardest questions answered). Studying for the GMAT is more than just trying to read and memorize a bunch of facts- it’s about changing the way that your brain thinks about how to manipulate an equation or dissect an argument. And what better way for your brain to learn how to tackle a challenge than to give your brain more time to do so. In the middle of a test, your brain is rushed. You might have had to give up on the question halfway through or guessed on it immediately to save yourself time. But when you give your brain more time to discover that “A-HA! moment”, your brain is much more likely to recognize what to do the next time you see a similar hurdle. After you spend some time trying to solve it on your own, feel free to search for an explanation or a better way of solving a problem. However, you have to make sure that the explanation you read is something that you can do in your own head or your own paper come test day.
Which leads to the problem of what solution is the BEST solution. Any student who has worked with me over the years has heard me say the following- “I don’t care what method you use to solve a problem. But I do care that you get 
Even though the NCAA tournament finished up earlier this month, for the next ten months I will be thinking about college basketball whenever I see the first several powers of two. No matter what type of GMAT question you are dealing with, our minds are better able to work through topics that we are already familiar with. Probability problems make me think of gambling, weakening a GMAT argument becomes shooting down an argument from that crazy relative you only see at Thanksgiving, and anything dealing with the number 64 comes down to rounds in a basketball tournament. Here’s a few tricks on the GMAT where knowing your powers of two can save you some time and brainpower.
If you asked me where I learned my countries in Africa, I’d tell you that it was from watching 
For every five hours of studying combinatorics-type questions, the average GMAT student increases their chances of being able to correctly answer a question type that is found only on the very difficult end of the GMAT spectrum. Meanwhile, the same student will have to compute hundreds of basic computations without the aid of a calculator. For students who know how to quickly do these computations, they are rewarded with extra minutes that can be spent double-checking their work and critically thinking about whether their answers make sense. As BenGMAT Franklin might say- a second saved is a second earned on the GMAT… but it doesn’t matter if those extra seconds come from being faster at doing combinatorics questions or quicker at computations. So check out these five math tricks, learn the ones that you like, and practice them daily to give yourself some extra time to finish off that 37th and final quant question.
like we did in the previous article, you’ve wised up and decided to open your own sports book, gMATH. You decide to start simple and offer bettors a chance to bet on which number, 1-4, randomly rolls out of a bingo cage. You realize that the probability of each number being selected is 25%, but you need a way to translate this for paying bettors. In a scenario where four different people each put down $1 on each of the four numbers, one person would win $3 ($4 total – $1 they bet). So you place the very first odds at gMATH’s number guessing game at 3 to 1.
