Good job on 2-2 and 2-3! Do you know how to anger waves? That is the key to higher experience levels. Drop a level 1 gem bomb on a wave -- you get more monsters and more xp. You can do this as many times as you can handle on a single wave. Wait till around wave 10 or so to start, when you have a nice mana farm set up (a row of traps with oranges in them). Doing this you should be able to get the experience you need. It works well on both normal and endurance. It is *much* more effective than rushing waves -- dont worry about calling waves early at all at this point. Let me know if you need more help. Also, dont forget mana pool (if playing endurance, use it once you have a nice mana farm set up, skip it on the regular levels till you get deeper into the game.)
Once you hit 16 you'll likely breeze through those levels your having trouble with.
