<p>So I haven't been attending my CSU due to taking classes at a community college and I been absent from that CSU for 3 quarters. My question is do I have to reapply to that CSU or could I just go along adding classes for that CSU whenever I'm going back there.</p>
<p>You need to contact the CSU administrators, and find out what your status is. Pick up the phone on Monday, and call them and ask.</p>
