Our HS uses online [Parchment;] graduation was June 4 but grades 9-11 finish June 14 so I don't think any transcripts will be processed before then.
I expect 3rd week of June is the earliest given time needed for teacher grading and uploading of exam scores etc. Of course the online electronic submission is a big help.
When I was in HS [NJ - '84] our last day was usually June 23. No way those transcripts are getting to WP by July 3 if this is still the case.
Don't worry about official transcripts getting there by R Day as long as school knows to send them as soon as they are ready. Hand carry unofficial final transcript or 2nd semester grade report to R Day. That can be used for placement purposes until official transcript arrives.
