数学,经济学(会计),管理学以及英语(ENGLISH 1A)是最基本的.另外可能会要求修美国历史,演讲等(每间学校不同).我不清楚你是否先去美国的社区大学念书.基础课程如果在社区大学修学费是比较便宜.你不必太过担心,因为美国的课程不太难,不过你要语言过关.但是这是需要时间来适应的.毕竟全英教学对于中国学生来说有一定难度.如果你到加洲念书,会比较容易适应,因为华裔多,不懂的问题也可以问同学.但是,这也就会导致你的英文水平不能迅速有效地提高. 美国的大学数学等于国内高中水平.当然,如果你选择以数学为主修,一样会学高等数学.加油呀,我都在美国过着打工上学的生活,你一定会成功的.

  用不到,因为教学风格不一样. 学习美式交流日常用语. 突击一下听力

  第一个问题：当然有用。 第二个问题：1.找讲母语是英语的先生或女士交谈。身边没有也没关系。到了美国用不了多久语言不会成为问题。关键是文化的差异会让你感到很多不自在和诧异。

  那得看你上什么了？高中还是大学 ，， 不管上什么 你学的知识都是有用的。，国外和我们的教学体制不一样的 他们有好多课我们都没有学过比如 （高中）会计 经济，，，大部分出来的人都学数学 还有比较偏理的课 因为这样可以避免英语不好的短处，，化学物理。。 你现在的英文是什么水平的 ? 如果不是很差就没问题了 出国会有语言班，， 然后找个美国人家住下 这样就会提高英语水平了 还可以了解西方文化，，，

  如果你打算今后到国外读书，我认为到美国最好。因此，建议你现在就参加中学生交流计划去美国呆上一年,一年后刚好能申请美国的大学。高中时就出去，不但更容易过语言关，对了解外国文化也非常重要。要知道很多英语讲得好的中国人在国外生活好几年，都只能跟当地的华人打交道，没有真正的外国朋友（文化差异大，跟外国人没有很多可聊的话题）。参加中学生交流项目，不但提高了你的英文水平，了解了外国文化，拓展视野，最重要的是你这样的经历有助于今后申请美国的大学。而且如果你学得好，还可以申请美国大学的奖学金。否则的话，到美国上大学，费用较高，另外，申请美国大学读本科，签证率很低呀。你可以看一下他们的网站www.asse.com 高中生欲申请进入美国名校攻读本科并想获得奖学金者，都必须保证SAT有很高的成绩，也就是说你想在高中毕业以后去美国上好的大学并且申请到奖学金，那必须考SAT，而且必须分数很高。如果你家庭情况不是特别理想，那就尽量的争取奖学金，只要你的SAT成绩比较好，是可以申请到美国奖学金的。你可以看新东方的SAT 培训很贵的，都在四五千左右                          下面是美国留学签证必答题集锦 1) What will you study in the United States? 2) What is your major?
