Transferring with only prep. classes

<p>So i have been reading heavily on transfer rqs. to UCB and i am a physics major. The igetc as i have been reading is more for people who dont exactly know what they want to do with their lives, and the prep work is for people who already have a major and school in mind. My question is, if i complete all the prep work for my major, as well as all the reccomended course work for it, what would be my chances of being accepted to any UC but specifically UCB? (This is all assuming i would have a competitive gpa obviously)</p>
