(words about experience points here)

Gaining a Level
When your character gains a level, you gain the following benefits: You add this amount to your current and maximum Hit Points. Your class skill is the skill that was assigned the +3 bonus during character creation. (Physical for the soldier, Knowledge for the mage and psionicist, Communication for the priest, Subterfuge for the scoundrel, and Survival for the hunter.) Roll 2d6 once for each of your ability scores. On a roll of 10+, improve that ability score by +1. If your Strength score improves, your maximum Hit Points improve too.
 * +1d6 Hit Points.
 * +1 to your class skill.
 * +1 to two other skills (or +1 to one skill and learn a new language.)
 * Ability score improvements

Ability scores greater than 18: When raising an ability score past 18, roll 3d6 and use the two lowest-rolling dice. On a roll of 10+, that ability score improves by +1.
