I would also suggest you make copies of anything that you can. We, too, had sealed envelopes which we could not copy. We sent the entire packet certified, kept checking the tracking number on line...according to the postal service, it never got there! We were so upset, thinking about how son would have to run around and ask everyone to re-do the work they had already done. However, he spoke with his admissions officer and they verified the package was received--even though the items are not crossed off on line. So, my advice would be to call before the Nov. 1 deadline, just to be sure. It will be a weight off your mind!
