1.- Is it true that the early questions count more in each section of the GMAT?
YES, since this is a statistically sound test. The computer is taking a sample of your performance on the test. For any variable with a normal distribution (GMAT score) the bigger the sample, the smaller the standard deviation, variance, and in this case “possible score range.” As you answer questions, the computer recalculates the standard deviation and “score range”, thus zeroing in on your score. However the relation is not linear, as the standard deviation is not a linear function. In other words, the early questions count the most and the last ones the least, so long as you finish the test.
2.- How important is it that I finish each of the sections on the GMAT?
It is critical that you finish each section. Since the computer is “programmed” to finish taking its sample of your performance on the test, it will count unanswered questions as if they were wrong at the beginning, in other words, where they count the most. This is why GMAC claims that the value of the questions at the end is not less than at the beginning; it is equal when they are unanswered. So, when you have a couple of minutes left it is not a bad idea to guess at the remaining questions, making sure that you finish the section in under 75 minutes.
3.- In which area of the GMAT will it generally be easier to improve my score?
Because of the nature of Math, improving the quantitative score through systematic methods will generally be easier for most test takers. Verbal seems harder because test takers perceive more than one answer choice as correct, although looking for patterns and approaching these problems in a step-by-step fashion has been shown to produce excellent score improvements.
4.- In the quantitative section of the GMAT, how many questions are problem solving and how many are data sufficiency?
On most tests, the mix is 60-40%, PS – DS, respectively.
5.- In the quantitative section of the GMAT, what is the most important skill I must develop to be proficient?
Reading, without a doubt; the most common “careless” mistake is misreading or misunderstanding the question. On data sufficiency, translating words into math expressions can really make a difference. In problem solving, using the answers to eliminate predictable or non-feasible options can also help to make an educated guess.
6.- What are the hardest quantitative questions on the GRE?
Most test takers have difficulty with a special type of data sufficiency problems for which the question posed requires a yes / no answer. When this format is combined with number properties or inequalities, the questions become challenging. Sound strategy and a systematic approach to these problems can help in their effective solution.
7.- In the verbal section of the GMAT, what could be the bottom line?
Definitely paraphrasing; paraphrase the question, paraphrase any other portions that you read including answer choices. Make sure you understand everything you read so you can assure a good answer.
8.- How can I do better in grammar questions?
Having a check list for errors is helpful when you cannot find anything wrong. Make sure that you do not skip any word and that you carefully read. Also, you need to go over the list in a fast way, so you need to practice this task.
9.- What do you recommend in order to be faster in reading comprehension questions?
Never read the whole passage from top to bottom and try not to do a summary of the passage before beginning the questions. Attack each question and each passage as it comes. But, DO paraphrase what you read.
10.- Can I just skip the essays so I can concentrate in the two sections that will render my score?
Each institution is different as to how much weight it gives the essays, but it is not recommended to skip them. A copy of your GMAT essays will be sent to each institution that receives your scores, so a bad image could work against you. Find out whether the institution that you are applying to is very or little interested in your GMAT essays before you decide to do something like that.
