I made a mistake on my UC TAG application...Need help!

I am a student from a city college, and I am planning to transfer to UCSB in fall 2017. I have finished 59 units of courses include this semester(fall 2016), and the problem is I forgot to add the courses that I need to take in spring 2017(Because the requirement is 60 units). I can only update my application after the Tag cycle, but that will be too late. Is there any way that I can fix the problem?

Try contacting the UC App support team. You can email or call them.
