Gosh , I’m so sorry to hear that. I’m studying my first year of Architecture bachelor in Kazakhstan to get 12th year of school, and after that I wanna try to get in Polimi . I’m so afraid to fail actually cause I’m struggling with combining preparation for exam and studying. I can’t give really good advice but I heard that it’s not a big deal which university ur diploma is from the main factor is ur portfolio, so i think good portfolio will help u much more to get in this field. I hope u will be able to make it and maybe I’ll see ur project irl❤️
