<p>you need to get 60 units and be considered a junior.
However if you want to start the UCSB experience earlier, then you should consider enrolling at SBCC. You can live where UCSB students live after their frosh year, take part in campus activities, and even take a class a quarter at UCSB while still a SBCC student. See my post in the UCSB forum a while back for more discussion.</p>
