A lot of new content has been added since the beginning which gives a ton of extra XP. Also, if you have currently done every single side quest, that will give you more than enough to be "Over-Leveled" for your school quests.
Nothing wrong with that, most of the time, if you are doing side quests, you will be over the level you need.
Am I too overleveled? i am lvl 23 and haven't finish firecat alley yetAs you can see , I really like to help people, i've done, trial of spheres three times, helped my friend with most of azteca, the chancel twice, did the tree of life, and beat the Jade Oni three times.
