Do you need an AD-T (Associates Degree for Transfer) to Transfer to UC?

Hello, I attend De Anza College and want to transfer to a UC. De Anza College offers an AD-T (Associates Degree for Transfer) for Economics. Some of the courses needed for De Anza's AD-T aren't even one of the requirements listed under UC's major preparation courses. As long as I am following the UC's major preparation courses at Assist.org, is it even necessary to get De Anza's AD-T? Will getting an AD-T increase my UC transfer admission chances? https://www.deanza.edu/counseling/pdf/degrees/degrees17-18/transfer_economics.pdf http://web2.assist.org/web-assist/report.do?agreement=aa&reportPath=REPORT_2&reportScript=Rep2.pl&event=19&dir=1&sia=DAC&ria=UCSB&ia=DAC&oia=UCSB&aay=16-17&ay=16-17&dora=ECONACCT
