<p>Does having a letter of rec from a professor at the school you are applying to help with admission? I am planning on applying for Admission at USC and I happen to know a professor. Would having a recommendation from him help with my admission? </p>

As in you “happened” to work for him/her? Otherwise, you’re wasting everyone’s time. The only meaningful rec letters are from those intimately knowledgeable about your actual work/service/scholarship/team play.</p>
