I was thinking about sending everything certified, but then I didn't want to risk annoying the admissions offices. They're swamped enough as it is, the last thing they need is to have to sign for every little thing I send them. I figure I'll just put my faith in the postal service, and then call up the schools a couple of weeks later to verify that they received everything. What do you guys think? Also, how expensive is it to send something certified?
