It's not fast EXP, but it is nice, AFK EXP. Usually get about a level in 20 minutes.
Load up the level with the two bosses (Dual something). Here, you have three options:
1) Control the MC and have that shield that heals you periodically.
2) Control Yangus and use his X spell to make yourself invincible.
3) Control a character that has the heal periodically accessory.
Now, do nothing. Just stand there. Your AI partners will kill all the enemies, but they will not kill the bosses because you have to get the last hit on the bosses. Adds will spawn for ~20 minutes, but then they won't come out anymore.
If your party is too weak (taking more than 1 damage), bring Jessica.
Come back 20 minutes later, kill the boss, everyone gets a level or two, and you get a few mini medals. It's not the fastest, but if you're cooking dinner or whatever, it's free XP and medals. I work from home, so checking on it every half hour isn't a big deal.
