你先申请学校吧 专业看你喜欢什么 专业太多了 例如econ bus criminology computerscience engineering iat linguistic 多了去了你申请好学校你可以去问他们的advisor 你要是学习能力不错你就申请工程师 会计这些以后工资可能会高的专业 好的大学雅思成绩6.5录取还有高中成绩平均80以上 这些上下会有浮动因为看是哪类大学 基础第一年必修就是宏观微观经济学 数学 英语 还有一些能体现写作能力的课程 比如哲学社会学 然后第二年就逐渐要修自己想学的专业课了期间可以修选修课凑学分

可以给我提供美国大学公共关系（PR）专业的排名吗？是本科的哦。

目前并没有公共关系的专业排名，原因还是美国公共关系PR专业一般开设在传播学院(College of Communication)下面，而美国TOP100名校中，开设此专业的只有十几所。学校很少，自然也没有排名的必要。不过我可以列举一些该专业比较知名大学给你，比如：
Georgetown University，University of Texas,Austin，University of South California，New York University，Syracuse University，University of Florida，Boston University，University of Denver等。
