<p>i'm an international student and our senior grade system is quite different from yours, and it may seem really poor if using your GPA system. (to be honest, my grades had fell a little)</p>
<p>What I'm questioning is that, if i'm already accepted by 2 US colleges (1 is top 50 and the other is 80+), but my mid-term report is not that good, is there any possibility that the colleges accepted me before would change their decision?</p>
