What are my chances?

<p>I graduated in 08' and was accepted and attended my freshman year at UCI. I had to leave the school because of my low gpa and from there went to a community college. Since then I have bounced around to three different community colleges. The first one I attended also kicked me out because of my low gpa/w's. Basically I kept going downhill. I did pass a few classes here and there but I have wasted about five years. I know I can retake the classes to replace the failed grades on my transcripts but what really are my chances of succeeding? These last two semesters I've improved but I think I've wasted too much time. Is it even worth it and what would I have to do to be eligible to transfer to a UC?</p>
