transfer students how did you submit your college report, mid term report, and high school transcript? I'm so confused and lost

This has been stuck in my head and I need someone to answer this. Did you guys just tell your advisor to fill out the common app college report and email it to BU or did you attach it onto your common app application? same with high school transcripts. Did you guys just email your high school counselors to email it to your colleges? Did you have to paid??
