<human>: First of sorry if this is the wrong subreddit.

So the College (UK) I applied for in January (on paper when I was taking a Taster day) sent a letter in January that I completely forgot about until today and just found it.

First off, it had misspelled my name by putting a 's' at the end of my name - don't think I wrote that on the form but then again that was over 5 months ago. The letter also asked to send a email which I just did today (I know late...) to confirm.

So in the email I put Student ID, My name (correctly) and the course name. Now the course name is: EDEXCEL L3 SUB DIP IN IT however on the website this isn't a valid course or at least not what I want, so I put next to it the Course ID of which I want which is "Computing - Software and Game Development.".

I feel like I screwed up somewhere, I can't exactly delete or edit the email and it is causing anxiety to me. Even the email has made it a ... thing as if it was a signature, I'm really confused and stuff and would like help. I would assume the email is automated but I'm not too sure, also on the site it says to put D.O.B but the letter doesn't.

Should I have sent a email with clarification on my correct name spelling, what course I wanted and stuff? I don't get my results until August and I have to enroll by going to the building, correct?
Literally nothing of all this is clear. 

I am going to a "Student Day" at the end of the month so should I talk up there? - which is hard for me.

--- So can someone clear all this up for me and what I should exactly do, thanks :)

Can you give me the gist of the text in a nutshell?
<bot>: College sent letter, I confirmed but probably done wrong. On the letter name is misspelled and course isn't the exact one I wanted.
