SAT/ACT required for transfer applications?

<p>does anyone know if your ACT/SAT scores are required when applying to transfer?</p>

<p>the Umich website only says it may be required depending on the number of credit hours earned in college, but no specifics on what that number may be </p>

<p>and if required, will i need to send them again or should they still have my scores on file from an earlier freshman application?</p>
