2 views of Japan's instrustrial management strategy (compared with 泰勒的科学管理 and one neutral position.
One view thinks Japan's instrustrial management strategy is good and it is close to 泰勒的科学管理. Another view thinks Japan's instrustrial management strategy is different from 泰勒的科学管理 and is merely an assembly line.
Third view is a neutral one, saying it is either good or bad. But the skills requied by the workers give them bargining ability.

That is all I could remember.

A couple of suggestions:
1) Concentrate on exam. Once finish one question, forget it and work on the next one. Never try to guess when I did right or wrong on the previous question based on the new question. It is too much distraction. I did not do well on this one.

2) Relax. No need to panic. The more panic, the greater reverse effect on your score.

3) Prepare to type on the worst keyboard. All the keyboards I used are better than ETS's. Their keyboard is very soft and my wrists are sour after the typing. A lot of typo mistakes since I do not like the keyboard and I am neverous.

************
I took two-week off to concentrate on GMAT. That score is so so and OK since it pretty much reflects my English level. If I want to get a better score, I need to improve my English. No better way around since luck is not always on my side. If it does exist, I hope it could show up when I buy a lottery ticket. :-)

But, my dearest comrades, good luck to ya!
