Chance an international student for U-M and U of T with a 27 ACT score?

<p>Please give me some advices for my applications.
I'm a international student from China and has two years of chinese high school education and two years of american high school education.</p>

<p>GPA-3.85 UW
ACT-27
highest english score:28
math :32
reading :22
science :28
Writing :08
* Will universities look at the highest component scores or just the composite score?
I took ACT three times, should I sent all of them to universities since I didn't get highest component scores at once?</p>

<p>TOFEL:103</p>

<p>I am taking AP Calculus AB, AP Physics C, and AP Chemistry, and I think I will get 5 or 4 on them.</p>

<p>Activities: Foreign Exchange-junior
48 volunteer hrs-senior
Chior-junior
Class representative-freshman</p>

<p>good essays</p>

<p>want to major in Business, computer science, or art</p>

<p>I'm not confident with my ACT scores and my activities...</p>

<p>Thank you very much!</p>
