My Asian GD got into WUSTL 2 years ago RD with a very similar profile to yours. NU is a harder hill to climb. You’re qualified for both, but these schools have so many applicants that it becomes a numbers game to the point that there’s a lot of luck involved.
On their common data set, NU says that rigor of your HS classes, grades, and class rank are the most important factors in their decision making process.After that, they look at your essay, recommendations, extracurriculars, talents, and personal qualities. So, do a good job on your essays, get good recommendations, and take your chances. They say that they consider test scores but don’t place much importance on them.
WUSTL is a little different. They place equal importance on rigor, grades, class rank, AND test scores as well as essays, recommendations, talents, and personal qualities. A little further down are extracurriculars, first gen, volunteer work, and work experience. So, they look at more factors and their cut off us a little lower but still daunting.
