<p>My freshman daughter receieved a 4 or 5 in AP Euro, AP Art, AP US History, AP Spanish, AP Eng comp and AP Eng lit thus she started with 24 credits. She received 3’s in 2 others so they don’t count at USC. With her (Dornsife) major and a language minor, she can graduate in 3 1/2 years with no summer school and no semester more than 16 hours. Also, she did get an earlier registration time. I’m sure it depends on your major and the school but in 1985 I graduated college in 3 1/2 years (no summer school) as a pre-med Biology major due to AP credits. Money and time well spent.</p>
