Hi Erlow,
I'm from the pharmacy forum. Oral and written communication skills are definitely important, not only to admissions, but to the pharmacy practice in general. I would suggest taking a communications class because it is required by all the pharmacy schools in CA. Make sure you can write a decent essay for the interview with proper grammar and sentence structure. Since you have about a year of preparation time, try to do some mock interviews with friends or relatives and practice writing timed essays on various topics.
Some schools will require you to write a thoughtful essay on an ethical issue, while other schools will want you to write a summary of an article. It really depends on the school.
Good luck!
