Punchap,
I recognize that this thread was started as a question regarding the application to the PCC program, but I have some unsolicited advice for you. As far as PCC/CPC goes - I don't think it matters so much which you choose - both turn out SOBs like Student Doctor Roe (just kidding, Sean). I would, however, recommend that you consider other schools altogether. OUCOM is in the midst of making changes in the requirements for scheduling 3rd/4th year rotations. These changes will make it difficult for you to complete rotations at hospitals outside of OU's CORE. This, in turn, may limit your choices for post-grad training programs. Other programs (e.g. DMU, Kirksville, etc.) are much less restrictive in the scheduling of 3rd/4th year electives, and thus their students have greater choice in visiting other programs. Something to consider.
