How long does it take to get to level 120 in Maplestory

It all depends on:
1) How often do you play maple?
2) How many hours a day do you play?
3) Where exactly do you train?
4) Is the rate of exp gaining excellent for you in your training area?

If you play often, train hard, train in excellent places for your level and good exp amount, you will get to 120 at an amount of a could months to a year depending on how slow are you.

Like me... I didnt like training so i neglected training hard and didnt bother trying to level quick. I often went to hang out with my buddies and since I'm a student and need to go to school, i could go on maple as much. I've been playing maple for 5 years now and is only 112 Priest. Slow isn't it? DO NOT WORRY! I doubt you're as slow as me! I regret that i wasted my time instead of training hard because i hardly have time for maple now and can't play as often even if i want to. If i trained hard enough, I could get to 120 from level 1 when maple first released in NA in 2 years minimum.

Good luck training! You tend to level faster if you have determination and a goal to meet.
