Two things u need to do to maximize exp:
One: Reset psp clock to ur bonus day
Second: Buy all the CPU level caps in the system catalog and the villian Ex-Death in the character catalog.
Go to quick battle, set Ex-deaths CPU to the highest difficulty possible. Start battle.
You don't have to win since even if u lose u still gain the exp u just have to hit him and u will gain 1000 exp each hit (not counting the bonus day).
The reason for Ex-Death is cause hes really slow and easy to hit.
