Questions regarding MA CS admission

<p>Hi,
I have been considering going back to school to get a Master in CS. I don't have any CS background in my undergrad, my major was Business and my GPA was really low, at 2.6. My questions are:</p>

<ol>
<li><p>Is there anything I can do to increase my chances for admission? I want to go to UCSD, UCI or other top schools.</p></li>
<li><p>How valuable is a Master CS from a California State University? Their admission requirements are much more lenient, and they offer a conditional basis for someone like me who has no CS background to take classes to get ready for the programs.</p></li>
</ol>
