USC has a great track record with accepting transfers from CA community colleges. Your recent accomplishments will definitely help. I would contact admissions, but understand that right now they are working through freshman applications. Here’s some info I found online in about 30 seconds (so do your research before you contact them, including knowing which counselor covers your geographic area).
