GMAT@7/17 AWA +math JJ
    

I did my GMAT yesterday at Dallas. I feel very sick after the exam but
I still have to do it again. T.T

During the last section, it is very hard for me to concentrate and
still think
normally. My pace slowed down significantly after 2.5-3 hours.  I have
the
same situation when I did my practice test. I did not see anyone talk
about this problem here. What is the case for you guys? Is there a way
to overcome
this?

Here is some JJ, hope it will be helpful to the rest of you.

AA is about a grocery store called Green.?.. is trying to increase its sales.
It usually attract wealthy people by providing luxury and expert service. Now,
this store is trying to cut down its 10 employees per store, and decrease its
expensive product and free samples.  In addition, it is going to corporate
with another coffee shop share the same target of customers.

        

The other one is "Best teachers should expect students to challenge
popular ideas instead of accepting it".

        

Math: what is the result of square root of 36^2 -25^2?

        

There is a line in x-y plane, with slope of -1/5, and it passes through
(s,3)and (?,s-2). What is the value of s?

        

there is one question about reminder, I don't remember the exact #, but the
method is similar to the ones already in this month's JJ.

        

I have a question about retaking GMAT. Is it not allowed to retake GMAT in the
same JJ month? I want to retake it at Mid-end August before the fall semester
starts, is it possible for me to do?

        

I also encountered the following:

        

        

        

 1        
1/41+1/42+1/43+1/44 范围；

我是选 >1/11

4     给5个字母：ROEDR，记住，2个R！问2个R中间至少隔2个字母的排列方式有多少种，18，24，……我选了个18，至今不知道对错。

19    20/2^5=1/2^m+1/2^n,求mn，我选3，m、n一个为1，一个为3

同意

20    版本1：有一个公司开会啥的，要么是stock holder, 要么是employee,要么都是，好像是stock holder有67%， employee是42%，问是stockholder不是employee的。 Both=67%+42%-1=9% 那答案就是67%-9%=58%

       版本2：有一个公司开会啥的，要么是stock holder, 要么是employee,要么都是，好像是stock holder有64%， employee是48%，问是stockholder不是employee的。
        

（1）都是的占30%（不确定具体数值）

（2）都不是的9%（也不确定具体数值）

必须31天之后

Sorry for late reply. Pearson's enviroment is not bad. Everyone takes his/ her own test in a cubic. However, there are different people taking different tests at the same time, so we are not able to see the pace of other test takers of GMAT. Here is also no people there to remind you about the timing when you take a break.

I took my test in afternoon. This may not be a great idea for me. My advice is to take the test in the period when you fell the most energetic.
