MattG728- You do not need a leter of intent for Communication but you will for PR. You do also need at least one letter of recommendation for Annenberg from an academic, college instructor.
Allow me to rephrase... it's clear you really want to attend Annenberg. But if you apply to two majors in the same school, the first of which is slightly easier to get in, and you don't get into the first one, there's probably no way you'll get into the second harder one & that'll be the end of the road. But it'll feel really great to go to the first academic advisement appointment and be congratulated on being one of ~75 out of ~800 to make it.
Here are a couple of resources that helped me out in the process:

Communication is also the only major within Annenberg that suggests taking Statistics. Suggested=do it. All of the new Annenberg transfers I met at Orientation had everything done. Don't forget your third semester of a foreign language either, that's a must!
