关于Notre Dame MBA early decision的问题

allennuli

准备申请ND的第一轮，可是在学校网站发现了这样一段话：
Early Decision candidates who are offered admission will have up to thirty (30) days to arrange their one-time, non-refundable deposit of $6,000 and will be expected to remove their applications from all other schools and refuse any future offers of admission from other schools. Applicants who are not prepared for this level of commitment are encouraged to apply in later rounds.

是说给了offer一定就要去是吗？像Columbia那样？
问题是notre dame万一不给奖学金的话，学费超级超级贵啊，两年13万美金~~

这是否意味着我应该申请第二轮啊？请有经验的CDer指教~~
