ADVICE NEEDED Edinburgh College of Art Graphic Design Portfolio

I would really appreciate any advice from graphic design students, or people who have heard back from particularly edinburgh university, what to include in a graphic design portfolio. I have been rejected from my first application from this course, but instead of going to my insurance university, have decided to take a year out to build a stronger portfolio for applying to Edinburgh again next year. (My heart is set on this uni). I would love to see examples of portfolio work or even how to even structure a graphic design portfolio of the standard for this uni. I would really appreciate the help!

Have you read this? It's not specific to ECA but it gives a lot of really good advice:

Yeah I've had a read of this thread ������ it is very useful! However it would be helpful to see graphic design portfolio content.
