Baldur's Gate II: Shadows of Amn Tips

Fast Leveling
At the early stages of the game it can be frustrating having your main character or primary few characters at low levels. There is a simple yet effective technique to ensure you gain levels as quickly as possible early in the game, which is as follows:

When you complete a quest disband all party members so the your main character and maybe one other character are all that remains in the party. Your main character will then get all/more experience from the quest. This means you can level up quicker, giving your main character that extra edge in the early stages of the game.
