Thank you for your kind response!(´；ω；｀)

I want to study about complex systems or chaos theories.
They are something like a mix of mathematics and computer sciences.
But,it maybe impossibe to work on them unless I graduete from an university and learn sciences enough.

At first,I have to study mathematics,programing,electronics and etc...
Also,I'm thinking to take a philosophy class because I had no chance to learn it in my high school.
Anyway,I must do my best in my university.

Universities I apllied to are all distant from my house.
I have been to one of them to take its own exam.
The univeysity I visited was so attractive and large but I'm not sure whether or not I've passed.OTL
I've already been admitted by another university,so,at least,I can be an university student this year.(＾ｑ＾)

The ACT and the SAT seem to be like the NCUEE in Japan.
But,NCUEE is offered only one time in a years.TT
Universitise in Japan generally choose students according to combinations of the scores of the NCUEE and each university'exam.
It's also the case that high school grades or extra-curricular activities or so can be considered,but this is minority.
In most cases,whether we are admitted is all and only determined by the scores of that two exams.
So the stress of that times was just owesome....

But,this maight be good for me because if I had been asked "What kind of activities did you take part in after school?",then I would have nothing to say except"Through strolling in 2ch and niconico,I have learnt a lot about the Inter Net....."＼(^o^)／
