WOOT! 800Score.com Math practice test - 710!!! [#permalink] New post 20 May 2008, 09:20
Just shouting out with some excitement. I'm getting ready to retake the GMAT on June 4th (pondering pushing it back 2 weeks). I just got done taking an 800Score.com Math section and got 24 of 28 right for a 710! I spent 4 hours last night reading over comb/perm, and overlapping sets. The questions I got wrong were mostly due to misreading what the actual question wanted.

One question said dividing a number by 3/8 then multiplying by 5/6 is the same as dividing by what? I answered 20/9, but that is the answer to "the same as multiplying by what number". The inverse (9/20) is the correct answer.

Another quesiton was that a train can go 15 miles per ton of coal empty, and 80% of that fully loaded. How many tons of coal will the train use to travel 160 miles fully loaded. I divded 160 by 15 rather than by 12. Just a stupid mistake.

The 3rd one I got wrong was just not following through on the question correctly. I got it set up right, but executed poorly. -->

The average of x, y, and z is one-third greater than x. The sum of x + y is what percentage greater than x?

I did x/3 + y/3 + z/3 = 4x/3 {hard to draw fractions here}.

That's the same as x + y + z = 4x

Bring the x's on the same side and get Y + Z = 3x. There is the answer, plain and simple 3 times, or 300% the value of X. BE SURE NOT TO OVERCOMPLICATE A SIMPLE PROBLEM!!!

The second question on the test was a grouping question involving a number of employees in a company. I used a tic-tac-toe grid and got it right.

I'm absolutely stoked about retaking the GMAT now. This is a 97% correct. The first time I took the GMAT in late April, I got a 66% on quant, and 84% on verbal for a 650 (82%) overall. Armed with the stuff from this forum and some good solid prep, I think 700+ is totally within reach!!!!

Wow, I took the GMAT the first time with little prep just trying to get into the local state university's mba program. It's a good regional school, but not really recognized outside the midwest. When i got the 650 on the first attempt, I looked around and found this forum that has been awesome.

As you can tell, I'm very happy with this.

Can anyone give me an idea as to how the quant on 800Score.com compares to the quant on the real thing?
