I also tried to get an extension to get more experience for retaking CPJE, but got denied. Same law they used to shoot me down, in a nutshell said: if you are eligible to sit for CPJE, then you can't get an extension. It irks me b/c i didn't want to waste time and effort with fingerprints/stamped affidavits/ signatures for hours/money... so i had called prior to doing the application and spoke to a rep who did look at my file then clarified with the "manager," and they said to do the application, (at the time i was already CPJE eligible), i think they just wanted my money. >_<
I'm not sure that the 4x fail, requalifies you for an intern license though. i wouldn't want to go that route either way since, you gotta go back to school ...it's already gonna be a lot of headache and stress trying to reapply to those specific Pharm schools.
