From what I understand from a call I made to my counselor with the same question, 7th semster transcripts aren't required, but they wouldn't mind seeing them. I don't know if it helps your WCS or anything, but the admissions people would look at it and react accordingly. Meaning if you're getting good grades with a nice courseload, they'll keep that in mind. So if you have even a report card or progess report, just fax it in and they'll put it in your file.
