First, I am convinced you will not find better instructors than the ones that teach at UNW. Most of them have prestigious academic backgrounds; one in particular has both studied and taught at MIT. More than that, each of them is not just teaching as a profession, but as something they genuinely have a passion for. I remember my Calculus instructor responding to the question of how he goes about teaching math like this: "I do not teach math. I teach students... a little math." Nothing delights these professors more than to have personal, deepening relationships with their students.
Second, the quality and depth of the education a student receives at UNW is as unparalleled as its instructors. Everything is taught in meticulous yet gripping detail, and not just from one certain point of view. Northwestern is a Christian university, but thanks to the diversity of the concepts taught I have a deep knowledge of things like evolution, atheism, Buddhism, Islam and several other ideas that conflict with my own beliefs.
Third, Northwestern tries its very best to keep student expenses down to an affordable rate. Just last semester, President Cureton came out onto the stage during chapel and announced with a smile that he had decided to freeze the price of tuition for the upcoming school year. The applause and cheering was deafening! Not only that, but if students work hard and keep their grades up, UNW offers GPA-based scholarships that are very helpful. Overall, you would be hard pressed to find a college that lives up to the standard of the University of Northwestern.
