Columbia Engineering Fall 2018

Hey everyone! I thought of starting this thread for all of us applying RD to Columbia Engineering for Fall 2018. I think we could get to know and help each other throughout the process. Although I already have two pretty good non ivy league offers for Spring 2018, I’d still like to apply to Columbia. My score on the new SAT is 1420 (I know it’s pretty low for Columbia), SAT subject test scores 780 for Maths 2, 700 for Chem. Have a pretty good list of extra curriculars. Don’t have any gpa as school didn’t follow the gpa system but I have all As in my A level subsidiary exams. What do you think my chances are?
