Star Wars: Knights of the Old Republic/Experience

Main player characters receive experience points (XP) for the following:
 * Advancing quests
 * Killing enemies
 * Using some skills (particularly and )

Kills
Experience received from kills depends on the Challenge Rating (CR) of the enemy killed and your main player character's experience level (not character level):

For example, if your main player character is currently level 2 but you have enough experience to level up to 8, when you kill an enemy with Challenge Rating 5 you receive 150 XP, not 450 XP (so you cannot level up more quickly by saving levels).

You can receive experience from enemies killed by any allies, even if those allies are not members of your party (for example, repaired droids). However, this isn't recorded in.

Computer Use
You receive experience from many operations involving throughout the game, and you also receive it from enemies killed as a result of these operations (although you aren't notified of it, it is recorded in ).

Repair
You receive experience from many operations involving throughout the game, and you also receive it from enemies killed by repaired droids (although you aren't notified of it, and it isn't recorded in ).

Stealth
As far as is known, you only receive experience for using once in the entire game: 300 XP for sneaking past three Sith on the Endar Spire's Starboard Section.

Level up
Receiving experience allows characters to gain levels. Experience needed for next level = 1000 * current level:

Characters can gain levels up to maximum level 20. ../Party/ members gain 80% of the experience gained by the main player character, regardless of whether or not they are in the current selection: for example, upon becoming level 20 with 190000 experience, party members have 152000 experience (so they are only level 17 since 153000 is needed for level 18). Thus the main player character needs at least 237500 XP for party members to gain level 20.

Saving levels
For all but the main player character, whenever enough experience is received to level up, doing so as soon as possible is recommended. However, the main player character starts as one class and later chooses a class, so the more levels gained with the starting class, the less can be gained with the Jedi class (and vice versa).

You must level up once to progress beyond the of the Endar Spire, but after you've gained level 2 you don't have to level up any further before becoming a Jedi, even once you've received enough experience to gain multiple levels. Before you choose a Jedi class you'll typically have received enough experience to gain level 8 at most; even if you're able to gain higher level with your starting class, this isn't recommended as level < 12 Jedi are not granted Master Sense (+2 ) or the highest level of their class feat.

Since maximum level is level 20, the choice is normally between level 2-8 starting class and level 12-18 Jedi class. Since saving levels can make ../Taris/ (much) more challenging, remaining at level 2 isn't recommended except for experienced players who choose to become a (since this gives them more ../Force powers/ earlier and in total, and more  to use them for longer and regenerate more out of combat).

Level 5 starting class and level 15 Jedi class is a popular choice, since all starting classes can select a feat at level 5 and all Jedi classes can select one at level 15. However, more experienced players may choose differently depending on a number of factors.
