@Rottgrrl : No supplemental for CSULA (unless you applied for Nursing) or CPP
For SLO: All transfer students are required to submit a supplemental application. It will be available on the MyCalPoy portal between January 4, 2020 and January 31, 2020.
For SDSU: Transfer applicants are required to submit a supplemental application through the SDSU WebPortal. Must be submitted by January 22, 2020.
Since this is past the deadline for the supplementals, check your application portal to see if transcripts are required prior to the decisions or you can update directly on the portal. You can always call admissions to confirm but since decisions are coming out shortly, the winter intersession grades may not make a difference.
