Princeton University was established in 1746 as a private college. It boasts a total undergraduate enrollment of 5,422, a suburban environment, and a 600-acre campus. Princeton hosts a variety of events, activities, and organizations inside the confines of its ancient ivy-covered campus. Undergraduate students are obliged to submit a senior thesis or, in some engineering departments, take on an independent project, which is a distinctive component of Princeton's academic program. They have a generous financial aid program that ensures that all accepted students, regardless of financial need, can attend and graduate debt-free.
