Principles of Finance for CDC

I am choosing my event for States and was thinking to switch from PMK, which I did at districts, to PFN. I got an 89 exam + 99 role play for districts but saw that last year there were 300+ for PMK in NC and only 115 for PFN, hence the switch. Any suggestions? Also what is the qualifying standard or amount that goes to ICDC and any scores to shoot for? Thanks
