I'll give you some hints, from levels 1 to 11 Solo your stages ( NORMAL MODE ) and do ALL your quests. from 11 ONWARDS party up + add people that are in your party to your friends for bonus 5% multipled by the amount of friends in your party as bonus exp, then do harder modes for extra exp, Thats how I hit max cap ( 16 ) in CBT in less than 1 day ( about 9 hours ).
