Weight of ACT in admissions when transferring?

<p>I want to transfer from UMich Flint to UMich Ann Arbor (main campus) my junior year. Does my ACT matter even if its substantially low? (21) will this hurt my admission chances? I have a 3.8 at UMich Flint and the admissions rep said the college im trying to attends average GPA for transfer students is 3.5. </p>

<p>Thank You. It means allot.</p>
