it will take much longer. You have already applied once so you have to understand the process.
yea, it could be tricky when applying online BUT you will have a slot there to attach a "Letter of explanation" form your computer
.
ANYTHING that you think should be attached to your online application should be in that file.
Just remember that everything have to be in
single file (
multi- pages) (transcript, SOP - if no a separate slot for it there. Also, for example: your parents financial statements AND their affidavit of support).
So scan all the papers you do not have a separate slot for in online application into
single MULTI-pages file, and attach that file there.
