Above average chance for an offer of admission to Northwestern University if you apply ED is my best guess. Tailor your application essays to particulars regarding Northwestern.
But, as much as I am a huge fan of Northwestern for hard-working brainiacs, I do not want to encourage you since you plan to assume massive debt. Better to attend Northwestern-Kellogg for an MBA if you want an entree to the top management consulting positions. Don’t assume more than $60,000 of personal debt for an undergraduate degree. Although there is substantial value in an undergraduate degree from a top 10 National University such as Northwestern, I advise against taking on significant debt at the undergraduate level.
FWIW There are schools for which up to about $80,000 of debt is justifiable for those targeting high-demand, lucrative majors such as CS. Northwestern University would be among those schools especially if planning to earn one of the Kellogg Certificates available to high achieving, hard-working undergraduates especially if targeting management consulting.
