USC 30-Credit-Requirement Question

So I’m planning on applying to USC this fall and I am a little confused at what they mean by “Needing 30 units completed” so you’re High school grades and SAT scores aren’t needed/considered. Do they literally mean you have to have already completed 30 units by the time you send your application (Which for me will be this Fall 2017)?

I’m asking because I will only have 23 credits done by the time Fall starts, and I’m planning on taking 14 credits in the Fall. So by the time fall ends, I’l’ have 37 units. Will they still need me to send ACT/SAT scores?

this confuses me as well. but someone told me i think as long as you’ll have 30+ credits by the end of the spring semester you will be fine. i’m not quite sure tho…

i plan on transferring as well and i totally do not know where to start.
