what are the possible reasons that UCI rejected me?

Hello, everyone. I am a female student who tried to get into UCI.
I applied to film and media studies.
I have 3.8 GPA. I submitted TAG to UCI and approved.
However, I could not get accepted from them.
If you know well about transferring to UC and their system, please tell me what are the possible reasons that I could not get accepted.

Thank you. Actually, I am an international student.

@YKNMKN Are you currently studying at a California Community College?

Yes. Im currently going to college in California

I would call admissions and ask them directly why you were not accepted if your TAG was approved. Did you meet all the TAG requirements after the approval such as completing the required courses and maintaining TAG eligible GPA?
