I am feeling the pressure too, trust me! I think you have a really good chance; as good as any. Your GPA is stellar and your scores are average for BC, which is good. I have heard that they really value their supplemental questions, so if you feel confident in yours then that is definitely good. I also applied EA to the college of arts & sciences. Good luck, maybe we will be future classmates! Would you mind also taking a look at my post, I would really appreciate it!
^^^^^^ The link is to chance me on all of my schools but you definitely don’t have to. If you could look at it for BC I’d be so grateful
