Let’s talk about perfect gmat score and, as a result, we will offer several advices regarding all GMAT questions, focusing on advices about how to prepare for your tests. If you’re given one or more conditions for a number (that it has to be prime, for example), make sure that the number you pick meets all of the conditions. But be careful to avoid making assumptions beyond these conditions. For example, if your question states that a, b, and c are consecutive numbers, you can’t then assume that a<bb>c. All you know is that they are consecutive—you don’t know the exact order in which they each occur. Moreover, you don’t want to pick a number that represents a possible exception to the general rules of a condition. For example, 2 is the only even prime number and can lead to some confounding results when worked with in an equation, so you may not want to choose it as your “plug-able” number in a prime numbers question. The last rule of thumb is to plug in numbers that are easy to work with. Don’t use a crazy number like 163—the whole point is to make the problem easier! As long as they meet all the rules of the conditions given (and don’t have their own confounding special properties), simple numbers like 3, 4, 5, etc. should be fine.
Pick up ‘mental math’ skills: Doing math in your head can serve you well. “The entire time you are preparing for the GMAT, resist the urge to reach for the calculator whenever you need to do some real-world calculations,” suggests McGarry. “Learn the tricks to doing mental math (It’s way easier to add 59 + 27 by adding 50 + 20 and then 9+7; then add the sums together.)” Have a strategy for sentence correction questions: To get the correct answer in sentence correction items, you must first find the wrong ones, says Yim. “Eliminate commonly tested errors in other answer choices until only one remains,” he adds. “Many times the correct answer will not sound great but that’s not the goal; you are trying to pick the error free answer.”
Let’s suppose that you live in a city large enough to have a decent population of private GMAT tutors, and let’s suppose that you’ve collected a list of tutors from Craigslist or gmatix.com or Google or some other website. (And let’s suppose that you’re not looking for an online GMAT tutor, otherwise you would have called the number on the sidebar, right?) So how, exactly, should you go about figuring out which private GMAT tutors actually know what they’re talking about? Before I continue, let me be painfully honest about my own history as a private tutor: when I first started teaching GMAT lessons at a major test-prep firm more than a decade ago, I barely knew what I was doing. I was always a lively teacher, but you really shouldn’t have hired the 2001 version of GMAT Ninja; the GMAT is an incredibly nuanced exam, and it took some time for me to truly understand how to help my GMAT students succeed. I worked hard at my craft from the very start, but I know—with the benefit of hindsight—that I wasn’t the world’s best GMAT tutor when I first started out. Read extra details at GMAT private tutor.
At the beginning of the test, your score moves up or down in larger increments as the computer hones in on your skill level—and what will turn out to be your final score. If you make a mistake early on, the computer will choose a much easier question, and it will take you a while to work up to the level you started from. That’s why you should make sure that you get those early questions correct by starting slowly, checking your work on early problems, and then gradually picking up the pace so that you finish all the problems in the section.
First of all you have to make sure that you are in a very good shape: starting with two days before eating and hydrating properly, you sleep on time and enough. Plan your time so that you have as few activities as possible during the learning period. The form you are in will largely determine your endurance. Secondly, you must have study conditions: an airy and very well lit place (preferably natural light to stimulate attention), quiet, and avoid contact with “equipment” (phones, computers ..) or people (parents or friends friends) and talk) that will interrupt you. Attention is very important, and interruptions are a major impediment to concentration. Source: https://www.gmatninja.com/.
