Canadian vs. American university grading

<p>I'm applied as a transfer to some top US colleges. I have already been accepted to UNC-CH. One of the things I am worried about is that my grades will drop once I transfer. Could anyone that has been in both systems share his experiences? </p>

<p>Here is the grading system at my university. It looks harsh, but I think it may be because the quality of students is not very high.</p>

<p>University</a> of Alberta</p>

<p>How different will it be for me?</p>
