What are the uses of percentages?
There are so many uses it boggles the mind. I will list a few, and perhaps people will add to it over time. * Setting and calculating discounts on sale items at the store * Calculating sales tax * Test scores (percentage correct) * Political polling Rates, and percentage is just a rate (per 100), are useful wherever you want to express one value relative to another value. Percentages become especially useful if you want to compare groups on a fairer basis. For example, if Student A gets 18 questions out of 20 correct and Student B gets 21 questions out of 30 correct, which is the better student? Student B answered MORE questions correctly, but Student A is better because they achieved a higher PERCENTAGE of right answers (18/20=90%). Student B's score, expressed as a percentage, is lower (21/30=70%). But if I had 2 questions and answered them both correctly, I'd be better (2/2=100%)
psat practice?
Perhaps the first most important test of a student's high school life is the PSAT. Not only does it supposedly prepare the student for the real game, the SAT, but it also carries a great deal of notoriety in and of itself. For one, there are many scholarships associated with the PSAT itself, as well as many opportunities that will open immediately if a student attains a top score on this test. Many academic institutions use the PSAT as well as the SAT to choose who to begin courting for inclusion into their programs. As such, the PSAT should definitely not be taken lightly, and actually, even though the P in PSAT stands for "practice," the PSAT itself deserves a great deal of practice before actually being taken by the student as well. As the PSAT is essentially a shorter and easier version of the SAT, it is actually appropriate to study for the PSAT using SAT materials. The increased difficulty of the SAT will serve as an "ankle weight" does to a runner - once the weight is removed, the legs seem even more limber because of the added pressure and more difficult practice. Also, having the student take the much longer SAT will prepare him or her for the shorter PSAT as long as the guide or tutor informs the student fully of the technique that is being employed. The tutor should tell the student to check back over his or her answers with the extra time that he or she will have. As with the SAT, the PSAT math section is arranged in order of easiest question to most difficult question. What this means is that the student should not skip questions when it comes to the math section, and the student should also begin checking over his or her answers from the very beginning so as to clear out the easy mistakes from the earlier questions. Because an easy question and a difficult question are worth the same amount of points, trying to answer a hard question instead of three easier, earlier questions will result in a lower score. The English section of the PSAT should be studied like a book report. The questions that are asked on the PSAT will mostly require the student to interpret passages. Also, vocabulary lists should be incorporated into the practice sessions at each meeting, with the intention of expanding the student's vocabulary each time.

GMAT Questions?
The Graduate Management Admissions Test or GMAT is a standardized test that is used to measure the aptitude to succeed in business school at the graduate level. Most business graduate schools require that applicants submit their GMAT score in order to be considered for admission into any of their business programs. The GMAT is a computerized exam that takes an average of four hour to complete. It tests students in both mathematics and english and measures their verbal, mathematical, and analytical writing skills. The maximum score than can be achieve on the GMAT is 800. The mean score however is a 542. Those who are preparing to take the GMAT typically are curious about what GMAT questions will appear on the exam. Even though every exam contains different questions, students can prepare for the GMAT by learning the format of the exam and what types of information that they are expected to know. The GMAT contains 41 questions on the verbal section, including critical reading, sentence correction and reading comprehension. These questions must be answered within 75 minutes and students can score a maximum of 60 points. In addition, the mathematical portion of the GMAT consists of 37 multiple choice questions with a time limit of 75 minutes. The mathematical GMAT questions include problem solving and data sufficiency. Students can also score a maximum of 60 points on this section. Lastly, the analytical writing portion of the GMAT consists of two essay questions. In one essay, the student must analyze an argument and in the second, he or she must analyze a particular issue. Students receive 30 minutes to complete each essay and they are individually scored on a scale of 0-6. The total score of the GMAT exam is composed of all of the GMAT questions that were answered on each section. The exam is designed so that most students score somewhere between 400 and 600. Most universities do not require a minimum score for admissions, however, they will often let prospective students know the median score of applicants. Students who wish to gain admissions to a top business school will need to answer a great portion of the GMAT questions correctly since students of these schools often receive scores upwards of 700 on the exam.
