This is how I’d sort your current list:
Extremely Likely
Stony Brook
Likely
Union
Possible
Brandeis
Unlikely
Brown
Penn
Cornell
Princeton
Northeastern
Would you be happy attending Stony Brook or Union and can your family afford either of those options? I’d be surprised if you didn’t have other options come spring of your senior year, but there have been a lot of surprises the last two years in college admissions. If you’re happy with either of those, there’s no need to add more. But if you wouldn’t be very happy attending those, then I would consider adding schools in those buckets.
