I can’t answer any of your questions because none of us knows what formula a school comes up with and why people who have lower stats get in ahead of those who have higher stats. No one on CC can tell you what’s good enough, only the admissions officers know. I would recommend that you research other schools that have some of the same attributes that made this school attractive to you and your parents. Though you are applying again there is still no guarantee that you will be accepted in the Winter of 2021 and you want to have other options. Your parents being angry is not helping you or the situation. As I’m sure you know, no one is guaranteed or entitled to admission at any school. Good luck to you.
