Also, how do I fill out the PFAS? When I go on the website, it tells me to sign in but there is no “create account” option.
They will send you login info after receiving your application. You can not create the account on your own.
The admission is need-blind for US citizens, permanent residents, and may be a few other countries.
If you’re a domestic applicant, then no it won’t affect your chances.
If you’re an international applicant, then yes it will lower your chances as UPenn is not need-blind and does not meet full demonstrated need to international applicants.
