The real question is what word processing program did you use for this paper? Word? Notepad? Works? Wordpad? What?
You can do this as an attachment in an email or by copying it onto a "flash drive" (one of those little USB drives that you can use to transport files).
You can also upload files by means of certain websites if your teacher has given you the web address and whatever username and password you'd need.
Thank you for your answer on how to upload a document. I am typing the document on word pad and I would like to upload it from there.
