I want to apply for an art school that I'm really interested in but I could never get my portfolio together 💔

My teachers throughout the years didn't care about art more just the curriculum they are supposed to teach us- And I was in an AP class on how to make a portfolio but she literally said make your portfolio, no help, nothing. It was a huge let down

I mean they both sound good but I have trouble with color theory sometimes 😅 but I'll consider it thank you :]
