谢谢大家。M=5x V=3x T=7xx, I hope to help some of you tomorrow.

Sorry I cannot type Chinese. I will try. Sincerely, thank everyone of you.
Now 机经: 我看到有5题Math(only Aug), No RC nor CR 机经。2 题 SC.

AA first then AI, different from last month GMAT. Be careful!!!
AA-Ice cream store- The Frostbite National Bank should not give a loan to the new ice cream store because of the cold winter and another store lost 10% last yr.
AI- Technological and demand in service change: individual worker needs to adjust to the change. It's not the responsibility of government or business.

数学-
我的第一题:1/{2+1/(2+2)}= 4/9 old JJ- Easy!
我的第2题: 一个四边形,有一个直角,直角对面的角是60度(有图)。直角的两条边是2。求面积。(old JJ #34) 360-(60+90)=210. 210/2=105 then, Divide the 四边形 into two triangles- use 45-45-90 and 60-60-60 ratio to solve for the area. Ans:2sqrt3+2

10个苹果,8个好其余的是坏的。任意取出4个,都是好的概率是多少
8/10*7/9*6/8*5/7=1/3 JJ

某公司做桔汁,昨天Orange-nade (a drink's name) concentrate (浓缩粉),兑上水就成了果汁)和水的比率是1:1,今天这个比率是1:2。两天用了相同数量的concentrate. 昨天和今天的桔汁都卖完了,而且两天所得的revenue相同。昨天的价格是 $0.6一瓶,问今天的price是多少。Ans: 0.4 0.6(2x) = p(3x) =>解出p (old JJ)

3X+5Y=?
A:X/0.5+Y/0.3=8
B:X/0.3+Y/0.5=3 Ans: A (like old JJ)

我brain is not good- only remember two new ones. Some problems have too many words. Please be very careful when you see them. I only had 2 min 30 sec left.
我的第37题- 2^k is a factor of 1008. Find the largest value of K? K=6
有题问decimal repetition called period. eg:1/3=0.3333 so period =1, Ask for the longest period?我pick Ans: C=11/7 Just try C first, then you will know.

英文-我考不是很好 读化工的。RC-2 very long ones. 85,40,40,95+. When I saw the 95+, I gave up and guessed most of them because it was toward the end and no time left. 1st RC on #9, so don't worry if you don't see them on #3 or #4. No JJ for RC. ETS changed them this week. I remembered one is about Steam Engines- before in the 1700, steam engines were not very efficient and used a lot of coal. So not too many people use them because of the cost. Then in the 1800s, new efficient engines, Watt Engines, were built, and then more people use them. So resources become scarce. Two view points presented (careful). One question asked how the analogy can be made to today's automobiles and gasoline? The 95+ one is about women-I cannot remember. I skimmed through it.

SC-especially+noun vs. specially +noun. Please check the grammar. I picked especially because the sentence made more sense. It was 2-3 split. Not sure.
ability vs. capability- I picked ability to..... as the sentence made more sense.
just as so... just pick this one and the only one correct.
watch for both of.... parallel structures. (at least 3 on parallel structure, 我的第一题) so know them.

CR-shit, at least four of them are very long. Longer than OG and Kaplan. Some answers do not make sense to me, so I had to guess after wasting a lot of time. If you cannot find the right one, don't waste time! ETS 大白吃。

My thoughts- Don't have to read this; just my feelings. Last month I took GMAT for the first time M:4x V:2x T:6xx. Very mad at myself. I didn't finish math, so couldn't do verbal because I was so angry. I am an engineer but still couldn't do math. So I didn't study for two weeks, then I found this CD website through taisha.org. Very lucky to find this site. Thank you. I studied math JJ from Jan to now, and some verbal. My chinese is not very good but I tried hard to translate JJ. I went through OG on SC and CR again. Did two Kaplan tests:610, 630. One PR-690 (very strange format on RC). Again thanks to CD。Then I took the GMAT the second time. ETS has changed its patterns, so be careful and try to help each other succeed. Don't ever give up. As long as the desire and heart are there, you can fight ETS.
