Does Upenn require SAT subject tests?
No, but they recommend them.
If you had the means and resources to take a SAT 2 Test, they will probably want to see it. The removal of the SAT Subject Tests was to encourage students who didn’t have the financial resources to take the tests to attend Penn. Although they aren’t a big deal, if you had the chance to take a subject test, you should submit your score.
i ll put it like this: unless you come from a very underprivileged background and you literally cannot afford the subject tests or it would be a big strain on your/your family s budget, then you should definitely take them, otherwise it will be a considerable detriment to your chances of admissions. it is very obvious to the admissions committee based on your application and financial aid records if you can afford them or not.
in fact that admissions office has actually said that they give a lot of weight on subject tests since they have found them to be a very good indicator of performance of admits during their penn career.
A rule of thumb: treat any recommended tests as required for top selective schools.
