Programs that use Phorcas for the management of their PGY1/2 residency applications usually post that they want 3 letters of recommendation (aka references) in addition to there usual requirements. The question is what does a program do if they receive 4 references instead of 3 from an applicant? Also why does Phorcas allow applicants to add references to submitted applications before and after the deadline but not allow for removal of excess references?
