【求助】UIUC 发了两个录取通知一个无奖一个有奖

一只汤圆滚呀滚UID：3765054

昨天早上收到了UIUC MUP 的AD无奖录取邮件，自己还琢磨了很久要不要上论坛找找哭穷要更多奖的方法。

结果今天早上起来发现又收到了他家的邮件，只是变成了小奖......

我有点懵，明明昨天还跟我说很遗憾没给奖以后机会还有的是之类的。

请问有经验的同学们：学校可以发了AD之后还会毫无征兆地更改吗？今天这封该不会是发错邮箱了吧...？

昨天附件offer letter里是这样的：
While we are unable to offer funding at this time, please know that our campus has been extremely supportive of past MUP students, about half of whom complete their second year with some form of on- campus support – fellowship, assistantship, research appointment, or otherwise.

今天附件offer letter里是这样的：
With your admission, we are offering you a College of Fine and Applied Arts (FAA) Nonresident Scholarship worth up to $10,000. Available to exceptional students from outside Illinois, this scholarship will reduce your Nonresident tuition by $5,000 -- $2,500 per semester in each semester of your first year.  Please note that, should you obtain an assistantship with full tuition waiver in either of these semesters, the tuition waiver would supersede the scholarship.  This scholarship is renewable.  If you make acceptable academic progress during your first year, we will offer the same FAA Nonresident Scholarship for your second year.

还有一个问题，第二封说的这个奖金发放方式我有点不懂。

看第一句理解成一年发一万，看第二句又变成一个学期发2500到5000，那岂不是一年发5000到一万？为什么金额会有浮动？

最后那一句renwable的意思是表现好第二年还发一万，两年总共两万吗？还是说第一年只发一万中的一部分，表现不好的话第二年就没有了？

qwq家里经济压力比较大所以还挺在意奖金问题的，上面提出的问题跪求好心人解答！
