<p>Michigan gives some credits to students scoring 4s and 5s in APs. In the case of Chemistry (for LSA only as the CoE requires at least a 4)) and Biology, some students even get partial credit for scoring a 3 on the AP.</p>
<p>If you do well on multiple APs (at least 5 different subject tests), Michigan can grant you 20+ credits and it is definitely possible to graduate in 3 years.</p>
