Questions that involve the summation formula, whether on their own or one component of a more complicated problem, often trip test-takers up for the simplest of reasons: figuring out “how many items” are in the set can sometimes prove tricky. One way to avoid the headache of trying to remember the rule for each different kind of limitation (consecutive even/odd/other, inclusive vs. exclusive, whether the set starts/ends with an even/odd), is to simply employ a strategy that will quickly and consistently allow you to determine the number of items in the set: patterns.

Before we delve into how, let’s review the summation formula and when it’s used. The summation formula:

 ∑ = (# of Numbers in the Set)(Largest Number + Smallest Number)/2

With a growing number of schools accepting the GRE for the MBA, we constantly get questions about which test people should take, so here are a few considerations to help students answer that question of GMAT or GRE:

1. The Advantage of History. The GMAT is the gold standard for the MBA application. Institutions have no questions about what GMAT scores mean and how to compare them retrospectively to students in their programs both current and past. Only recently (the last half-decade) has the number of schools accepting the GRE increased significantly. Advantage: GMAT.

Every year about this time I get a few “Christmas Miracle” phone calls. The callers don’t see it that way, but that’s in essence what the calls are. These calls (or sometimes emails) usually start rolling in around mid-December, when people are nearing crunch time for second round b-school application cycles and frantic that their GMAT scores haven’t progressed to a point they feel will give them a reasonable shot at their schools of interest. Let’s take a look at the particulars of a couple such cases from this month.

For all prospective GMAT examinees struggling with the Verbal section:  Read!

Reading a quality periodical is one way to beef up your verbal score and maybe even have some interesting things to talk about during an interview.  Jargon filled articles with complex sentences and foreign ideas are very similar to GMAT Reading Comp passages, Critical Reading Prompts, and Sentence Correction problems.  Think about it this way: when you exercise,  varying your workout gives you the most bang for your buck as it stimulates different muscle groups and systems in the body.  This same principle can be applied to studying for the GMAT.  Look outside of traditional test materials to push yourself to that next level.

ETS informed the world in April 2012 that ScoreSelect was going to become available in July, and that option is just around the corner.

ScoreSelect allows test-takers greater flexibility in deciding what scores to send to schools. The move is part of ETS’ ongoing push for a more test-taker friendly platform, and will provide test-takers with the comfort and security of knowing that a non-representive score doesn’t ever have to make it to admissions offices at schools. This relief should allow more test-takers to go in feeling confident and put their best foot forward come test day.

The ScoreSelect option is available both on test day and afterwards. Here are the particulars for test-takers, straight from ETS:

With Round 1 application deadlines for many schools just a scant 3 months away, many people are revving up their preparation. One big component of the application process is the test score (GMAT or GRE) that most schools require, and a big part of any preparation are practice tests. In a later post we’re going to discuss how practice test scores influence when we should take the GMAT, but today we’re going to take a look at how practice tests (or an official score you’re not happy with) should inform your preparation decisions.

Before we get into discussing practice test scores, we should take a moment to clarify a few important considerations about practice tests themselves:

The sixth and final entry in the Word Challenge: Two Words, One Speech series, ends with our current commander in chief. Written by Bell Curves co-founder Akil Bello, this entry was posted on 4RIISE.com

In the final installment of our speeches series, I offer to you a man triply fitting for mention on this President’s Day. A man known as one of the greatest orators of our time. A man of historic stature and prodigious ability. This week’s speech comes to us from the first African-American President of the United States of America: Barack Obama.

Part V of our six part series examines the words of Frederick Douglass.  Written by Akil Bello, co-founder of Bell Curves, this entry was originally posted by Riise on 2/13/12.

In keeping with the theme of Independence Day, this week’s speech was delivered by Fredrick Douglass on that date in 1852. This speech is not only a great oration it also provides an interesting insight into the time and place of its delivery. Douglass had been invited to speak as part of an Independence Day celebration by the leading citizens of Rochester, NY. The line highlighted below shows not only the depth of his language mastery but also his opinion of the state of American “independence” and the arrogance of inviting him to participate in the Independence Day events, given that he was an escaped slave who had been freed, and was still fighting for freedom for all other slaves.

Fellow citizens, above your national, tumultuous joy, I hear the mournful wail of millions, whose chains, heavy and grievous yesterday, are today rendered more intolerable by the jubilant shouts that reach them. If I do forget, if I do not remember those bleeding children of sorrow this day, “may my right hand forget her cunning, and may my tongue cleave to the roof of my mouth!”

Written by Bell Curves co-founder Akil Bello, this entry was posted on 4RIISE.com on 2/6/12. Part IV of our ongoing Word Challenge series proves that great speeches can inspire and entertain.

Great speeches use deliberate language and strong vocabulary to sway the audience to a point of view, address injustice, or simply to inspire. We’ve looked a at few figures in US history who have done all those things and more. Not all great speeches happen in Congress or on Inauguration Day, however, or are even given by real-life people. Some speeches take place on Independence Day, or more specifically in “Independence Day” the movie.

Greetings and welcome to another installment of Akil on the GMAT. I thought I’d share some of my thoughts and advice on how to study for the test. It seems more and more I encounter people who are studying wrong (oops I mean ‘incorrectly,’ since an adverb is needed to modify ‘studying’).

First, to understand how to study properly you have to understand the nature of the GMAT. The GMAT is an adaptive test that assesses quantitative and verbal REASONING. As such, the GMAT is not a test that you get a great score by simply memorizing facts, since a reasoning test requires logic supported by facts, rather than simple fact regurgitation.

Regurgitating facts will most likely only allow you to get a score in the low to mid 500s (in the best case scenario). If you are satisfied with a score in the 500s, you should just get a list of formulas and rules tested and memorize them. [My marketing department requires that I insert a shameless plug here for Bell Curves flashcards, which give you a succinct, comprehensive list of the rules and formulas tested on the GMAT - all in a nice, pretty package.]

If you want to have a realistic shot at the higher scores, you will need to memorize the facts necessary for success on the test and then, more importantly, develop your ability to use those facts in context.
