Transferring after/during Junior year

<p>So I did a semester abroad my sophomore year. During the time I was abroad the University of California system had its transfer deadlines due. I was not able to apply.</p>

<p>Here I am applying to schools, though to be honest my chances seem a little bleak. I am being realistic; I was actually being optimistic when I decided to apply to a school.On top of that there are some schools I firmly believe I can get into but am wary about financial aid.</p>

<p>So lets say it didn't work out. I understand I there's a transfer course limit as well as minimum number of units I need to take from certain schools to get degrees.
Does anyone have experience transferring in from junior>senior year?
How do you feel about:
-getting involved in the community
-getting accustomed to the school</p>
