Because someone else commented on price, keep in mind the Ivies (and all of the schools in the QuestBridge program) match your financial need (usually according to the FAFSA, but you’re also required to fill out the CSS Profile for the Ivies). That means you don’t have to take cost into consideration when deciding whether to apply there.
