Be Mindful About What DS Questions DON’T Tell YouHi Rich,
I found this DS question tricky. What should I look for so I don’t get similar questions wrong?
How many integers x exist such that a < x < b?
(1) b - a = 7
(2) a and b are integers
Moana
Hi Moana,
This DS question is built around a test of your thoroughness. Notice how you are NOT told anything about A and B…..? You might have to think about values that are NOT integers…
We're asked how many INTEGERS are between A and B. This is a perfect question for TESTing Values
Fact 1: B - A = 7
If B = 8 and A = 1, then the integers between them are 2, 3, 4, 5, 6, and 7 (a total of 6 integers)
If B = 8.5 and A = 1.5, then the integers between them are 2, 3, 4, 5, 6, 7 and 8 (a total of 7 integers)
Fact 1 is INSUFFICIENT.
Fact 2: A and B are integers.
Since we don't know what A and B are, there's really no way to answer this question…. but if you're looking for proof….
If B = 8 and A = 1, then the answer to the question is 6 integers
If B = 2 and A = 1, then the answer to the question is 0 integers.
Fact 2 is INSUFFICIENT
Combined, we know that B - A = 7 AND A and B are integers. This means that there must be exactly 6 integers between them. You can TEST any set of values that fit these rules and you'll get the same answer every time.
Combined, SUFFICIENT.
Final Answer: C
GMAT or GRE?Dear Rich,
I took GRE last month and here are my GRE scores:
V162
Q167
AW4.0
So should I take the GMAT? And how different is the GMAT vs the GRE? Are there any causes for worry other than integrated reasoning?
Nora
Hi Nora,
The GMAT and GRE have a number of aspects in common, especially when it comes to content and tactics. There are some notable differences though:
The GMAT Quant section includes DS questions, while the GRE Quant includes QC questions (and multi-answer and fill in the blank questions).
The GMAT Verbal requires more reading, while the GRE Verbal stresses vocabulary knowledge to a much higher degree.
In General, GMAT questions are "longer", but give you more time to answer than GRE questions.
Since you have a really strong GRE score, you might be able to apply to your schools without taking the GMAT. I would suggest that you contact an Admissions Consultant about your overall application and plans.

I took GMAT twice and both the times I scored exactly same Q47,V23. Surprisingly, when I do verbal quizzes for cr and rc I do okay. But when I take the entire test, I don’t do well.
Olan
Hi Olan,
CR and RC prompts, like almost all GMAT prompts, are about patterns and repeatable steps. You might find an individual RC passage to be short or long, easy or hard, simple or complex…. but you should deal with it in the exact same way EVERY time. The Verbal side of the GMAT requires almost no imagination or cleverness on your part - it requires a cold, methodical approach. RC prompts require the same general approach regardless of the details because RC prompts are based on the same handful of question types.
CR prompts test a slightly wider range of thinking, but they too are based on patterns, common themes (and even common wrong answers). You should never "wing it" on a CR prompt. Identify the type of question that you're facing, then follow the proper steps to beat it.
From what you've described, I don't think that you were really focused on learning, memorizing and practicing the "steps" for RC or CR. With a V23 on your GMAT, you're also losing out on some SC points, so you might not know all of the grammar rules that are required. Furthermore, you could very easily be too fatigued to do the work correctly and the way with which you choose to handle the Verbal section might be leading to some pacing problems.
GMAT assassins aren't born, they're made,
Rich
