Math equations can be solved by utilizing appropriate formulas, following easy to memorize rules. The verbal section requires concentration and a mastery of English standard grammar. There exists a series of questions on the GRE, however, that require the use of all of your test-taking senses. Probability, combination, and permutation questions require an instinct for flags, flags that give away tell tale signs as to how to solve for the solution. Once you understand exactly what the question is asking for and why, the problem will seem as flipping a coin.

**Mutually Exclusive or Independent**

It is important to remember the difference between factors that are mutually exclusive and factors that are independent of each other. Say you are given ten boxes of chocolates, each box containing a different flavor. Imagine that chocolates containing nuts can only be found in boxes 6 through 10. If you would be asked what is the probability of selecting a chocolate from one of the first 5 boxes AND have the chocolate contain nuts, the resulting answer would have to be zero because boxes 1 through 5 don’ contain nuts. The two factors are mutually exclusive. If you were asked to flip a coin followed by rolling a 6 sides dye. The probability of landing on heads and rolling on a 6 are possible because the outcome of one event does not affect the outcome of the other. The two events are independent of each other.

**The Difference Between AND and OR**

There is a huge difference between the probability of two events occurring, or either of two events occurring. If you are asked to roll a die and asked what is the probability of rolling an even number and a number less than 4, you are still being asked the probability of a single event. This single event just happens to have more than one qualifier. There are 3 even numbers on a die, and 3 numbers less than 4. The number 2 is the only digit on the die that meets both of the given requirements. There is one outcome, out of the six total possible outcomes, that would work for our needs. Now say you were asked what the probability of rolling a number that is either a 4 or an odd digit. We are now asked to find the probability of two separate events. We are asked to find the probability of rolling a 4, and we are also asked what the probability is of rolling an odd digit. There is one outcome resulting in a rolled 4 and 3 possible outcomes for rolling an odd digit. Four outcomes would meet our requirements out of a total six possible outcomes.

**Permutation and Combination**

Always be asking yourself, how important is order? When entering the code into a pad lock the order of the digits is very important. If the right code is 144, 414 would not open the lock. This kind of problem is referred to as a permutation problem. There are 10 possible choices for each digit on the lock (in the case of this three digit lock we would need to multiple 10 by 10 by 10 to see the total number of permutations). You can also have a permutation problem in which repetition is not allowed. Say that once a number is used on that imaginary lock we discussed, it can no longer be used. In that case the options change (the first digit has 10 options, while the second has 9 as a result of one outcome being removed as a possibility, the next digit has 8 possible outcomes). To solve this sort of permutation problem we would multiple 10 by 9 by 8. A combination problem is one in which the order of the factors doesn’ matter. A lottery is a combination problem without repetition. The order of the numbers doesn’ matter and numbers can appear more than once. Say this particular lottery we’re playing contains 6 numbers ranging from 01 up to 49. There are 49 possible outcomes for each number drawn. Because order doesn’ matter we need to reduce the amount of outcomes that would exist in a permutation problem. The formula is 49!/6!(49-6)!

We have 49 options for each number and only six numbers are going to be drawn. Combination problems with repetition are a bit trickier. Imagine you are reaching into a refrigerator filled with 5 different types of sodas. If you would like to select only 4 sodas to take out, how many combinations of different sodas can be selected. The solution is derived from the following formula: (5+4 -1)!/4!(5-1)!

The reasoning is that all four sodas could be the same, or all different, or two the same, or three, and depending on which sodas are selected or excluded altogether.

The probability, permutation, and combination questions pose a lot of stress on test takers because they are very large in scope and design. They are questions about options and too many options can confuse anyone. The key is to visualize the problem, see it as a relatable situation, whether a combination lock, a lottery, or a refrigerator filled with sodas.

]]>College is over and preparation is under full way for continued education. Getting into graduate school is competitive and everyone hopes to be among the top candidates applying. It is true that a graduate level education is a step forward, however, don’t be fooled, everything you need to know in order to master the GRE exam is already in your lexicon. The best way to prepare for such an exam is to understand that a majority of what you should be doing is reviewing what you’ve already learned.

**Remember the SATs?**

One of the best ways to prepare for the GRE is to prepare for an exam you’ve already taken, the SAT exams. The quantitative and verbal sections provide excellent examples of what you might see on the GRE exam. Hopefully you still have your test prep books from several years prior available. Study the problems as well as your notes.

**Back to School**

High school math and English textbooks can be very helpful in preparing for the GRE. Just like studying for the SATs can help in preparing for the GRE, studying High school level math and English can help prepare you for the SATs. If you have any of your old high school notebooks feel free to give them a look over. The information you will be required to know will not be complicated, just probably forgotten. Refresh your memory of what you already spent so many countless nights cramming.

**Read a Challenging Book**

Atlas Shrugged is long and filled with vocabulary that will probably require the use of a dictionary. As you navigate through an interesting story you will also be adding vital information to your memory bank. The GRE uses language that one does not come across on an average day; this is why it is important to read text that will challenge us.

**Be a Mathlete**

Attempt to become competitively good at math. Work at not only solving geometry, algebra, and trigonometry problems, but also solving them at a competitive rate. The GRE is a competitive exam, everyone else taking the exam is competing with you for placement at a top Masters program.

It may seem simple and that’s because it really is. Grad schools aren’t interested in what you don’t know because that’s what they’re there for, to teach you the advanced information. The admissions counselors just want to be able to gauge how well you’ve retained the information during your academic career. If you never spent too much time studying and the quantitative and verbal problems you’re coming across seem like a foreign language then the GRE test preparation journey will be more difficult. Whenever preparing for an exam it is important to remember that the fault, as well as the responsibility, lies solely on your shoulders. The more effort you put in the better the results will be. When it comes to the GRE consider it a second chance to take an exam you feel you could have done better on in high school. The GRE is a second chance everyone should take advantage of.

- If you take it multiple times, all your scores will be evaluated by the admissions officers for your chosen programs.
- Some programs will put greater weight on the higher score and be more impressed by a significant increase in score than two similar scores.
- Other programs will choose to judge applicants by the highest scores in each section.
- Averaging scores is uncommon.

- The test is computer-adaptive, and leaving questions blank is very detrimental to your score.
- You will score anywhere between 400 and 1600.
- The national mean GRE score is about 462 in Verbal, 584 in Quantitative and 4 for the writing assessment.

]]>Be mindful that the format and point system will be changing by this time next year.

According to The New York Times, the test will be revamped and even extended in length, with a new grading scale of 130 to 170. The Educational Testing Service (“ETS”), which administers the GRE, claims the changes are the “largest revisions” in the GRE history.

So, what’s going to change?

While the exam will continue to include verbal reasoning, quantitative reasoning and analytical writing – all three sections are being revamped. In terms of the changes within each section, here is a breakdown of what to expect:

- VERBAL: The verbal section will eliminate all questions on antonyms and analogies.
- QUANTITATIVE: While there are several minor changes, there is an advantage to the quantitative section: an online calculator!
- ANALYTICAL WRITING: While this section will still have two parts, including a question for logical analysis and personal opinion. The questions themselves will be more focused, ultimately allowing the raters to know the answer itself wasn’t memorized, but was actually written in response to the question.

The GRE is unique in that it’s “computer adaptive.” What does that mean? Well, when you answer one question correctly the test will then take you to a more difficult question. Should you answer a question incorrectly, the test will take you to an easier question. The new GRE in 2011 will be three and a half hours in length.

**Why the changes?** It seems the G.R.E. is trying to keep up a presence with the GMAT, an increasingly popular test for graduate admission and business schools, in particular. While there were announcements as early as 2005 to update the test and lengthen it to four hours, those plans were soon cancelled due to delays in setting up Internet-based test centers. The plans were then cancelled altogether in 2007.

At this present time, the Internet version of the GRE lasts three hours, whereas the paper-based version lasts three hours and forty-five minutes. According to the New York Times, over 600,000 students take the GRE annually.

]]>Over 1,800 graduate business schools accept the GMAT and as a whole, it’s been the standard admissions tests for business schools for the past fifty years. The GRE, on the other hand, is taken by more than 600,000 students annually and it’s good for a five-year period. Let’s not forget cost: the GMAT costs $250.00 and the GRE significantly lower at a mere $150.00 (for the US only & effectively as of July 1, 2009).

Now, when compared back to back, the GMAT is the harder exam in terms of both the reading and math sections. For native English speakers, the GRE’s reading is slightly easier, although it could be cause for alarm for non-native English speakers due to the complexity of the vocabulary. As a whole, the GMAT is used for business schools and some economic schools while the GRE is used for more general graduate degree programs.

So with all this information laid out, one can’t help but wonder – where did the controversy come from?

ETS actually lost the rights to the GMAT in 2006, so since then they’ve encouraged schools to take the GRE instead. About 115 schools have complied, including Stanford, Johns Hopkins and MIT. The GRE seems to have added bonuses that the GMAT doesn’t. In fact, there is a new section on the GRE called the *Personal Potential Index*, where a mentor can fill out sections in regards to creativity, integrity and communication. Is the general consensus among graduate school professionals that the GRE is stamping out the GMAT?

Evidently not, according to David A. Wilson, head of the *Graduate Management Admissions Council*, who was quoted in a recent New York Times article on the topic. “**Schools turn to the GMAT because it is a valid, trusted and robust assessment.** One way to think about it is that you don’t want your dentist to buy drill bits at Home Depot.”

Where does that leave us on the subject? Our general advice is the following: know what schools you want to apply to before you go about preparing for standardized tests. Know which tests your universities prefer. Keep in mind, the MBA is still accepted by all major business and economic schools around the world. If you know you want an MBA, brush up on the GMAT. However, if you are leaning more towards a general graduate degree, the GRE is probably your best bet.
