Transferring to RISD

Hi all,
I will be a freshman this coming fall at an art school near where I live. RISD is my dream school. However, I was unable to apply as I didn’t have a portfolio. I opted to drop art in my sophomore year to allow for room for more AP classes (which is stupid, I know, but tbf I faced a lot of academic peer pressure as my high school was/is very competitive). I was wondering if anyone has any general comments/advice on transferring to RISD. I’m looking for things I can do this year to help my chances besides working on creating a portfolio. More specifically, I would like to major in architecture, so if anyone has any specific comments on architecture for RISD, that would also be greatly appreciated. Thank you so much in advance!!
