I would suggest that you contact those who run the tests (Pearson VUE, I believe) and find out. They should have customer service numbers that you can call, and this information should be on your confirmation email when you first scheduled your test. (I must say that this is a very unique situation ...

Woah... whatever you do, DON'T guess the last 7! The scoring algorithm is approximately such that for every question you get right, it gives you a harder question. If you get that right, it gives you an even harder question, etc. If you get one wrong, it gives you an easier question. And so on. The ...

(1) Square root of A^2 - B^2 is NOT equal to A-B! In fact, it has nothing to do with A-B. As you do know yourself, (A-B)(A-B) = A^2 - 2AB + B^2, not simply A^2 - B^2 (2) A^2 - 2AB + B^2 =1 From this we can deduce either of the following: (A-B)(A-B) = 1 or (B-A)(B-A) = 1 If the former is true, then A...

Obviously you figured out that neither statement alone is sufficient, so let's look at the 2 statements together. Notice that the number of children has to be a multiple of 10. Its ratio to number of women is 2 to 5, and its ratio to number of men is 5 to 11. This means that it needs to be evenly di...

I would say the answer is C. Of course this is not "official", but I'm pretty sure I'm correct. If you order all the projects by number of employees assigned, the "median" means you want to know the number of employees assigned for the project at the 50th percentile. Makes sense?...

(1/5)^n > (1/5)^-2 = N>-2 This step in (2) is wrong. If (1/5)^n > (1/5)^m, then n<m. This is true for all numbers between 0 and 1 (such as 1/5). Consider the following: (1/5)^-3 = 5^3 = 125 (1/5)^-2 = 5^2 = 25 ... (1/5)^2 = 1/25 (1/5)^3 = 1/125 So the greater the power, the smaller your result. Hen...

I assume you meant >= when you typed <= the two times. If you took GMATPrep more than FIVE times, those final scores are going to be very skewed since you would encounter more and more familiar problems. I recommend the Manhattan GMAT series of books for brushing up on the basics tested (minus the r...

Now I really need a whiteboard. I will attempt to explain this without one and see how it goes! Draw a rectangle on your paper. This is your sample space of 60 people. Draw a circle inside, label it A. This circle represents 48 people. Draw a circle inside of A, label it B. This represents those who...
