I just received the UCLA/Drew secondary application in the mail on Saturday. It is a four page application that you have to mail back. There is a $50 fee.
I did send in a UC Application to UCLA, but that was because I also applied to UCLA directly. Interestingly enough, the same day that I received the secondary (11/10), I also received a postcard from them saying that they had received unverified AMCAS information in the middle of August. The postcard was postmarked early November.
Anyway, it appears to me that UCLA/Drew did not begin the process until they received verfied AMCAS information.
