Crack GMAT in US, 01/22

2003-01-24 08:49:17

7**, 5*, 3*

First add sth I still can remember here:

1. Issue comes up first: each nation doesn't necessarily need to sacrifice its energy resources, instead, international leadership and cooperation are essential

2. Argumentation: Company A will fail because 1) millionare owners of Company B, which do same business as A in game, fail cause children are bored with game 2) too many games in US home already, lack of demand.

Sorry, I didn't go through every articles. Pls refer to AWA for details.

3. Maths: Not very difficult, but tricky, easy to fall into pitfalls. JJ helps familiar with 5-6 questions, but be careful, half percent is not exact the same. So understand method is most important.ETS tends to complicate context and increase difficulty for foreigner to understand. I met at least 3 questions talking about, for ex., a(subset) out of another targeted cross set. set could be male/female, who do/who don't, sorry couldn't remember.

1)I know clearly the last second problem solving is wrong. It's easy to understand but fail to resolve at that moment.

A spend 2 more days than B do to finish W Widgets. They spend 3 days tegether to finish 5/4W widgets. How many days it takes for A to finish 2W widgets? Answer: 6, 8, 10, 12...

2) XYZ axis plane. -6
3) DS:温度计题，有图，温度计上有4点好像是w, s, r, v(依次从下到上)，ws间0个刻度，sr间1个刻度，rv2个刻度. 刻度 is equally distributed. Ask w's temperature. 1) r+v = 30 2) s+v = 20 Answer: C (Hint: there's no direct indication of temperate)

4)what's the average of (n-w)+(n-x)+(n-y)+(n-z) ? 1) w+...+z = 4n 2) irrelevant Answer: A

Taxi, old jj, D) 12.08

2) BTW, although these Qs not appear in my test, but I want to share my opinion:

2、100个某东西，买来的时候30元一个，全部卖出后赢利1500刀元。其中N个以每个50元卖出，其余的以每个X刀元卖出。问X LESS THAN 40？
1）N > 60
2) N < 80
【确认】A

My answer is E, N could < 37.5

28. whether x<0? 1)x^3+x<0 2)x^3+x+1=0 (2次)

My answer is A. Still A if in 2) x^3 is changed to x^2 as there's no solution for both 2)

To be continued...
