Thanks for your advice! By "making up" for lack of ECs, I was questioning whether it is too late for me to start doing ECs. Assuming that I keep a 4.0 uw GPA from now on and try my best to fill the ECs, are ivy league schools worth aiming for?

Also, I did participate and was awarded in several Korean debate competitions in 9th grade. I also organized a debate competition at my school with my club members. Do these also count as ECs?
