<p>I do not think it is a waste of time at all. Princeton reviews their applications “holistically,” which means that they look at you as an entire package. This means that they will not just toss your application because of your lower SAT scores or lower class Rank. They will read your entire application no matter what. And do not freak out about the class rank thing. Those statistics have got to be a bit skewed because many high schools do not rank. Only a portion of the applicants come from high schools that actually rank their students. Also, even if you have perfect scores and grades, they still might not take you. It is all about what the school wants and needs. If they need more female engineers, than they will take girls who indicated they were interested in engineering with less stellar SAT scores than someone who has perfect SAT scores and grades but designated his/her interest as something that the school already has plenty of.</p>
