There are quite a few ways on how you can earn EXP quickly in the game. If you’re a player, the best way would be to clear through the story quests first.
These MapleStory 2 Mesos missions provide a good amount of EXP along with some useful items as rewards. Doing story quests is also a great way to familiarize yourself with the game.
Otherwise, you could always turn to side quests for some extra experience points instead. You’ll see if an NPC has a side quest if they have a blue exclamation point above their head.
If doing quests really isn’t your thing, you can also grind by taking on hordes. There are certain areas in maps where enemies will continue to spawn no matter how many times to defeat them. You can pretty much stay in that area and fend off enough enemies until you reach a certain level.
