I can identify with your situation.
What is your home state? Not all states have a flagship state univ ranked within top 50. You may end up paying OOS tuition if you go to UC or UNC.
I am curious that you are confident to get in schools such as NU, Princeton and Vanderbilt. Those are all reach school even for ACT 34 and 4.0 UW GPA.
I don’t think you are admitted to any of those schools yet as it is still November.
I would suggest you to get the admission letter first and decide when you have options. Right now all talks are academics.
