Fall is here! All Current Activity is due Aug 19, 2011 or is subject to a 2% late fee.
Reduce the Balance Due by any approved Fall aid, not already posted to your account.
Any unpaid Previous Balance must be received by July 21st to avoid a 2% late fee.

应该是学校账户有关的吧

大概就是说你现在的账户活动里所列出的项目支付的截止日期是2011/8/19，晚交要罚2%；然后你这个fall如果有奖的话，还没有显示在你的账户里；之前没交的欠款还款的截止日是2011/7/21，要不罚2%
