By the way, if you don't know what critical reasoning is, there are three types of problems in the Verbal section: sentence correction, reading comprehension and critical reasoning. I didn't suggest you concentrate on Math because you are already scoring pretty high.

Most people learn better in a classroom type environment, so it's great that you will attend the seminar. Definitely nail down those concepts, and you will do well. Just keep asking questions if you don't fully understand. Best of luck to you.

Damn you GMAT!! (660)

So I took the GMAT yesterday [10/01/08] and was stunned at my score.. 660... =( Granted I only gave myself a month and a half to take this bad boy, I really thought I would fare better than a 660, especially because I felt I was smoking through the questions (smoking through = getting them right). I...

The answer should be C. I don't know how to use type to draw a Venn, but I can try to explain. Please keep in mind that these questions have multiple possibilities. There are: 'Coffee Only', 'Dessert Only', 'Coffee and Dessert', and 'Neither'. Also keep in mind that you don't have to solve the probl...

I think this is 2.

At the start, the price is $81. After 6 months, it will be 1/3 of its price, or $27. At one year, it will be 1/3 of that, or $9. At 1.5 years, it is $3. At 2 years, it is $1.

I believe two years is the right answer.

Re: gmat prep F(x)

Thanks! You have to plug in for this one. I'll try to explain the question as clearly as I can. If f(x)=f(1-x), that means that wherever x works in an equation, you will get the same answer by substituting (x) with (x-1). This question does not give you a clear road map on what the answer will be (...

Algebraically, if you think about it this way:

a+b-ab=0

a-ab=-b (just reworking the problem to isolate a)

a(1-b)=-b (still working)

a=[(-b)/(1-b)]

And since you can't have 0 be in the denominator, the only way that would occur is if b=1. Therefore, b cannot equal 1, so answer is B.
