Let’s discuss about online GMAT tutor website and, as a result, we will offer some advices regarding all GMAT questions, focusing on advices about how to learn for your tests. Problem Solving Tip: Look at All the Answer Choices Before Solving: This is generally a better strategy than solving the problem right away and then looking for a choice that matches your solution, as the choices themselves can provide clues to how to solve the problem—especially if there’s a property or shortcut that can help you do so. For example, if a question appears to ask you to multiply many large numbers together but the answer choices are all in exponent form and are all an order of magnitude away, then you might be able to just estimate and find the closest answer. As always, the GMAT almost never requires you to do extremely laborious equations out by hand—they want to see that you can get to the right answer efficiently (as an excellent businessperson would)! While the IR section relies largely on the same math, verbal, and critical reasoning skills that you need for the other sections of the GMAT, there is one unique skill set that you will need in addition: the ability to interpret various graphics, like bar graphs, scatter plots, and line graphs.
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.”

Look for Wrong Answers Instead of Correct Ones: If you’re stuck on a question, be a smart guesser and use process of elimination to get rid of some of the wrong answers. Wrong answers are often easier to spot than correct answers. Sometimes they just sound weird. Other times they’re logically impossible. While it is rare to be able to eliminate all four of the incorrect answer choices on the GMAT, you will almost always be able to eliminate at least one of them. You’ll have a better chance of selecting the right one.
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/.
