Sending colleges all your application stuff?

They are used to everything arriving separately. The people who open the mail do not become angry when this happens. It is the reason that they have their jobs. Many of the mail openers are students who are working part time. There is no reason to worry.

Unfortunately, you cannot be assured that everything gets there at the same time. It's pretty impossible. The good news is that colleges understand this, and they have to. They made all the requirements for all the documents. They will set up a file, and when things arrive, they will add them to your file. I did the same thing applying to a second bachelors degree program. I was nervous about all my documents too. I kept checking in, and the lady at the admissions desk assured me that they will keep track of my documents. She told me the college gets so much mail every day, that it takes up to two weeks to be sorted. This is why they have deadlines. Lo and behold, a month later, I got in and my documents checked out.
