Clearing, please help?

Okay so the short version of this story is that I chickened out of applying to uni since I thought my art wasn't good enough and I had and would get rubbish grades in the exams.

Low and behold the results came and I did way better than expected and it was suggested to me by the careers officer that I try clearing.

So i've talked to dundee about their spaces in the Art and Design (foundation and General) Course, to see if they'd accept me on the grades that i have. I applied for something (It was early and I was a tad panicked, so don't know what it was =_= way to go me) and they've got back to me asking for a portfolio.

That's the problem.

I don't have one.

Well I kind of do, it's complicated.

So I have maybe a day to get my stuff together and send it off to Dundee. So I was wondering if maybe someone else has had a similar experience and could help me or even if you know what Dundee are looking for in a portfolio. The things that I have already basically show that I can do a wide variety of things.

If you managed to read that, thanks,

Fudge.
