If I send the transcripts by post, need I add piece of information, like my name, date of birth and online application usename, for the admission officer to recognize my application?
I have the sealed envelope with my transcripts. Since I am going to apply online, the transcripts are the only things I need to send by post.
i think you'd better attach a cover letter to make an explanation, that is, to explain you apply online and now send the transcripts required by the school. I think that will be fine! Good luck, MM!
