Arora, Selango, etc.... This problem/discussion should be flagged for all prospective gmat takers! So much of this test is about reading carefully and finding what the trick is in the problem. Every time I go through an official GMAT Prep Test with one of my students I am struck by how many of the q...

Hi saumiljacksparrow, You post an excellent question about "which" that is very important for success on GMAT Sentence Correction problems. Relative clauses (modifying clauses starting with relative pronouns such as that, which, who, whose, where, etc ) are one of the most misused structur...

When I teach work/rate problems I try to avoid any gimmicks and have students use the following approach, which will work for any work/rate problem: 1. Always convert times to rates. If times a...

hi kvcpk, the number of terms would not have mattered except that the average in statement 2 would have to be an odd number (as you probably know in data sufficiency the two statements cannot contradict each other). if you have a set of consecutive even numbers then the average will be odd if there ...

Another way to approach this problem is with a scenario driven strategy and understanding of the odd/even number properties (although the algebraic approach also works well here). If the three numbers are consecutive there are only 2 possible scenarios: x = odd, y = even, z = odd or x = even, y = od...

clammiestqasar, Strictly speaking, comma splices exist when two independent clauses are improperly linked with a comma without a coordinating conjunction. An example of a comma splice would be the following: Bill lives in New York, John lives in San Francisco. Clearly this would require some type of...
