Architecture at UofE

I’m wondering about what to include in my portfolio when applying for undergraduate degrees in Architecture. I’m most interested in The University of Edinburgh but also curious about the other four universities in Scotland that offer architecture (Strathclyde, GSA, Robert Gordon and the University of Dundee)
I’m currently in S5 and took Nat5 art last year (got an A) and I’m planning on taking higher in S6 as I wasn’t able to this year.
Any other advice or tips when applying would also be appreciated

If you have an art based subject I’m pretty sure Edinburgh don’t ask for a portfolio I’m an offer holder for Architetcure and they didn’t ask me for a portfolio I did higher design and manufacture and higher graphic design

Thank you so much and congrats on the offer
