GMAT re-take - verbal strategies
I wrote the GMAT on Sept 30, scored a 680 (49Q and 34V)-6 AWA. I took some time off and I'm planning to go back and re-write. The test itself went ok, I was very ANXIOUS before the test - couldn't eat, had to piss every 10 mins, etc. I tried to channel the increased anxiety to help me move quickly a...

Good call - question stem is exclusive of 0 and 2 while 1) includes them...
Since in 1) x can =0 or 2 we fall outside range in question stem.
Ans should then be E - agreed!

|x-1| < 1 so 0<|x-1|<1 hence 0<x<2 we need to find out if x is between this range exclusively 1) (x-1)^2 <=1 x^2-2x <=0 x(x-2)<=0 testing some numbers we quickly find that this range fits the bill of 0 to 2 so 1 is suff 2) x^2-1>0 (x+1)(x-1)>0 can have +ve * +ve --> x>-1, x>1 --> x>1 or -ve * -ve --...

Good question - you've altered the answer choices to ask a specific question, here's my interpretation: will continue ... once horns are trimmed will continue ... once horns have been trimmed This questions outlines a hypothetical situation, I think the present (are) is better, though I think the se...

A square is a rhombus. From 1, since diagonals bisect, can we not say that the quadrilatoral is a square? ...not necessarily, the diagonals can bisect to form a 90-degree angle without necessarily having a square. To prove to yourself draw 2 lines that intersect at 90-deg and make one of the lines ...

any line will intersect the x-axis at the point where its y-coordinate is = 0 so setting the equation below to 0 will give us the point where the line intersects the x-axis... ax+c=0 x=-c/a so the axis and the line will intersect at (-c/a, 0) now we need to know the value of c/a... neither of the an...

Is it "wrong" not to take notes during RC?
I'm having trouble with timing during RC questions. In order for me to take notes, I find the need to pause every 1-2 sentences, paraphrase the material on my page, then find my spot on the screen (which I sometimes loose) and resume. By the end of the passage I'm often far behind (time wise) that I...

Thanks - I'm aware of MGMAT's policy on this but I don't think it mirrors that of the GMATs. I could be wrong though. Anyone know the GMAC policy of leaving the last question selected on GMAT? I'm not planning on "zooming" through any portion, but it would be nice to get some time in case ...

What happens if GMAT times-out b/f clicking submit on last q
I heard that the GMAT will accept an answer on last question without physically clicking "submit". Is this true? If so, and assuming I can finish early ...I was thinking that in order to extend my break between essays and Quant and/or Quant and Verbal I would select the answer for the last...

the biker goes 20-4 = 16mi/hr faster, so he is gaining 16mi on the biker per hour...
16 mi/hr*1 hr/60mins*5 mins = 16/12 mi to catch up = 4/3 mi
4/3 mi / 4 mi/hr = 1/3 hr = 20 mins
hope that helps

absolute signs make any sign inside (+ or -) positive (+). So in your first example -M=|-M| we can simplify |-M| to |M|, so: -M=|M| any value of M<=0 works: -(-1) = |-1| 1 = 1 your second example must be 0: |P|=-|Q| 1 or -1 will not work because the absolute signs turn anything to a positive |whatev...

Good question - I actually fell for B as well... but upon reading the criteria that p and q are INTEGERS D is the right answer. the only way n^2 = P^2/q^2 can be an integer (when p and q are integers) is if the prime factors of q^2 are common with prime factors of p^2. If the squares are common then...

if rectangle has ratio of 2:3 then 2x+3x+2x+3x = 10x is total perimeter. Then square has sides of 2.5x = 5/2x
so area is (2x*3x)/((5/2*x)*(5/2*x)) = 6/(25/4) = 6*4/25 = 24/25
so B
hope that helps

The project required 10*110 = 1,100 man-days so whatever happens has to equal 1100 to complete the project we are told that of the first 60 days there were 5 days of rain, so: 55*10 + 5*0 = 550 (half way there) then we hire 6 people so up to 16 employees and work until day 100. Let's assume there is...
