Does your school have a PRSA chapter? Can you take PR or Communications courses as elective courses this fall? I would try to intern as well—and do not limit yourself to entertainment PR. Those internships are hard to get and filled for the most part by now. Look around at various agencies for opportunities (I post them every Friday.) If you are dead set on entertainment, however, consider BWR, CAA, ID PR, HL Group, Alison Brod, Rubenstein, 5W, Dan Klores, Rogers & Cowan… I could go on and on. Do some research and keep an open mind. Good luck!
