Does your school have any history with the colleges you are waiting on? If so, where do you fall in terms of class rank? Although your school does not rank, generally, how do you fall with regards to the other students in your school?
Looking at your schools, I agree, it will be unlikely at all the schools, but there’s a definite chance at Lehigh and/or Rochester.
The others are so extremely difficult, expensive (UCs), and unlikely. However, if your school admits 10 students a year historically at Brown and you’re in the top 5….then you might have a chance.
One other possibility could be NUin for NEU. That’s possible since they do not consider that as part of their acceptance rate. But the cost will be probably over $90K.
