if you go through your quests (pull up the map and then hit... L2 twice I think?) you'll be able to see which wasn't perfectly executed, I think the quest is shaded in a different colour or doesn't have three stars with it or something like that.

Possibilities of quests you didn't perfectly execute (these are the three that immediately come to mind for me):
-You can't let Salmon take any damage in that Junon escort quest
-Can't fail picking mushrooms
-Wrong meat for the condor

Had to retry battles more than once to achieve that first one which I'm banking on also being yours.
