so I got waitlisted for cc (sociology/poli sci major) and Columbia asked for a supplementary statement and I already submitted one with my recent updates and now I just got some new updates (just got an intern offer at a law firm, I'm not sure should I submit a second supplementary statement with that cuz I already interned at this law firm before and it was in my application material but now I got an offer again from this law firm this summer so idk should I include this and submit another loci or is it just repetitive. and if it's a good idea to submit again, then should I still submit on the portal or email them the updates?

also for transcripts, do we submit by parchment or email?

and at last can anyone give some advice for cc waitlist, I know the chances are not big but I still want to give it a shot. anything would be helpful!! thank you so much :)

applied as a freshman (full pay, international, major in sociology/poli sci) from a t20 with 4.0 gpa and 4.0 hs gpa (went test optional) decent ecs (I think...) research, leadership in club, intern, etc. got rejected from duke Cornell penn brown uchicago(got waitlisted for uchi when applied during high school and literally rejected as transfer...) waitlisted for Columbia and now only have northwestern and Yale left (no interview for Yale so I know there's no chance)

sorry for this long text but I just want to know is transfer also really dependent on luck cuz I literally thought I could get in at least one of them and I'm pretty confident with all my application materials ...

also I already submitted one loci on Columbia portal for waitlist and should I submit another one since I just got new updates?
