Transfer Senior Year

I am currently a Junior in high school and I am thinking about transferring high schools senior year. I have been wanting to transfer schools since freshman year but I haven’t had the opportunity to. I go to a private high school far away from my house, so I commute a long way, and I want to transfer to the public school in my neighborhood. I can’t decide so I figured the best way to decide would be for random strangers on the internet to give their insight! (Kinda sarcastic kinda not).

Pros of Current School:
-teachers know me
-involved heavily
-more opportunities available to me
-possible good teachers for senior year
Cons of Current School:
-miserable every single day
-long commute
-people are rude and snotty

Pros of Public School:
-closer to home
-6 class schedule
-possibly happier
Cons of Public School:
-don’t know anyone
-switching school senior year, new environment
-new teachers
-possibly the same or worse

I think the reason I can’t decide is that I don’t know what will help me get in to a good school. My current top choice is University of Notre Dame and I don’t want to screw up my chances going into senior year. I’ve already discussed this with a few teachers, my parents, and the UND representative for Southern California. This is a really difficult decision so I’m trying to get as much insight as possible.
