UC Application: I Missed a Course!

Recently I’ve just realized that I didn’t include my Theory of Knowledge course in UC Application because I was confused about which category to put the subject under during the application. I have emailed UC Application Center and they said I could email them a document of updated course and grades so they could share it with the UC campuses I’ve applied to. I also emailed each campus to inform them about the changes (and I also attached the update document with each email) but I don’t know if they will accept the changes because it’s already January. Is it certain that they will accept my updates for review?

Also, I read in UCSB website that any changes of school records should be MAILED, there is no mention about email and I can’t fine the admission office’s email. I’m an international student so it’s really hard to mail my update documents overseas. Does anybody know how I can contact with UCSB via email about my updates? Thanks!
