2017年Fall申请的话不用太着急。GMAT争取在明年Fall之前考出来就好了。美本的话是可以waive托福,具体要求:“international applicants who have not studied a minimum of six full-time semesters, or nine quarters at a university in the United States, must submit an English Language Proficiency test score”
ND是接受雅思的,quoted from admission webstie:" General Application Requirements: Official TOEFL or IELTS score report". 有时间的话我个人建议还是考一下T或者把雅思刷高一点~其余的话,因为ND会综合考虑你的分数和经历,所以在文书和resume中别忘了突出你的软实力~先修课是必须的,所以还是建议找机会补上,陆本federal taxation入学前会统一补
