How to level up

[Jedo]

In order to level up a pokemon you must battle with it. If it defeats a wild pokemon it gains exp equal to half the wild pokemon's level. For example defeating a wild level 5 rattata nets you 2 exp.

To level up the pokemon you must gain exp equal to or greater than it's current level. In order to level up a level 5 elekid you must gain at least 5 exp.

If you defeat a trainer's pokemon you gain exp equal to that pokemon's level.
