who received supplemental questioner? What does it mean?
It means that they feel they need further information to fully evaluate your candidacy. They often seek information on any factors affecting your education/situation or any special awards or programs that you may have mentioned in your application. I was told–and I have no way of knowing if this is true–that you will be admitted if they find your responses persuasive.
@maamir Are you a transfer? I’m curious if transfers are getting those. I hadn’t heard of any getting them.
I have not heard of transfers getting those. As a freshman they may want to get a better understanding of your profile.
@grimmghost ok, cool. I read that some other UC transfer applicants had got them, but I wasn’t sure if UCLA was sending any. I’m not sure I have any more personal statements in me, haha.
I remember from some of your other posts that you have an extraordinary story for transfer and I think they just want to get to know more about it and how you have evolved from your experience. Try to look on the brighter side of things, you did the best you can do and they are delving into the depths of your application! 
Best of luck
@grimmghost Yea, I mean, I feel ok about my chances. I think part of it is that I don’t want to jinx anything by being overly confident, haha.
Good luck to you as well!
