I have received a few acceptances so far, as well as some rejections, and waitlist spots, but I am still waiting to hear from four programs. One of them (Wright) I just had an interview at. Do you know when schools have to let us know by? I am just concerned because I need to let the other schools know my mid-April. Should I email the schools I have not yet heard from? Is it okay to ask the schools I was accepted at to extend the deadline?
