The GCs form is checkboxes. You are panicking unnecessarily. (One of my kids got a new GC senior year, too). It made little difference.
Also, deadlines for the school materials are a bit soft at most colleges. Get YOUR pieces in on time — app with essays, app fee, and test scores. But many schools won’t be fussed if the school materials come in a week or two late. They can’t review everyone’s info the first day anyway.
So… calm down. Check in weekly on the progress of any components you are waiting for.
