@Slavic2000 Do not substitute Northwestern for Northeastern - Northwestern RD admission rate is single digits. If the finances check out and it becomes your first choice, you might consider ED.
Schools that are more realistic for admission that might be feasible financially - run the numbers to see: Dickinson, College of Wooster, St. Olaf, Beloit, Earlham, Knox, and Clark U. Grinnell is a bit more competitive but might be worth a try.
Will you qualify for National Merit status based on your PSAT score (I’m not sure how threshold is assessed if you are non-resident in the US but a US citizen)? If so, there are some schools that are very generous like Arizona State and UT-Dallas.
Alabama-Huntsville might be a full-ride option, check to see what the qualifying test score is.
Nearly all of the schools on your list are very competitive. Try for a 1500+ SAT or 33+ ACT. Also check to see if SAT II subject tests are recommended or required.
I hope that Questbridge will work out for you because that also will boost your chances. Good luck!
