Here is some stuff you asked about:
"The Academic Update period runs from mid-November through February 1. AADSAS will notify applicants when the Academic Update period opens."
"AADSAS does not require you to participate in the Academic Update. Rather, this is a service that you can opt to use. The Academic Update allows you to provide your most recent grades to the schools to which you have applied. If you have already been admitted, check with your school to determine if they want you to participate in Academic Updatemany schools ask that you do so, so that they have your most recent grades on file."
I'm probably going to wait till after I get my fall grades (mid/late Dec) which by then I am hoping to be accepted. So I can deal with one school and just see what they want me to do. But I would rather just send my transcript at the end of the year with all my grades.
