The Penn core strengths essay is killing me idk why this feels way harder than a typical Why X. Like who I am as a person is really defined by...a value of professional development...and cross disciplinary studies...lol.
Just to add some confusion to how fee-waivers are decided; I don't have a reportable GPA (foreign) and I've received unsolicited fee waivers from Penn, Cornell, Vanderbilt, UCLA, as well as some lower-ranked schools.
Definitely JUST wait. Do not email, call or check on your status. Don't ask if they rank the waitlist. Schools often will update you so it's a "don't call us, we will call you" situation. Good luck.
