As the college admissions process becomes more and more competitive, what are the hardest colleges to get into? College-ranking website Niche compiled a list using Department of Education data, which included SAT and ACT scores of applicants, as well as acceptance rates. To arrive at these rankings, acceptance rates are weighted at 60 percent and SAT/ACT scores are weighted at 40 percent. By this definition, a lower acceptance rate doesn't always mean "harder" to get into. (All average undergraduate tuitions listed include room and board.)
